The reaction between hydrocarbons and halogens in sunlight is also on the core part of the <span data-scayt-word="programme" data-wsc-lang="en_US">programme</span> under <a href="../18597/alkanes-alkenes-addition-polymers-1.html" title="Alkanes, alkenes & addition polymers">10.2</a>. Students should <span data-scayt-word="realise" data-wsc-lang="en_US">realise</span> that saturated hydrocarbons can also <span data-scayt-word="decolourise" data-wsc-lang="en_US">decolourise</span> bromine water but the reaction is much slower and needs the presence of ultra-violet light. If it is a sunny day then it takes about five minutes in bright sunlight for the reaction to work. Iron filings act as a halogen carrier and speed up the reaction between <span data-scayt-word="methylbenzene" data-wsc-lang="en_US">methylbenzene</span> and bromine water. This could also be included if you wish but it is not required as an example of electrophilic substitution in 20.2. However it is much easier to do this practically than nitrate benzene, which is the example given.</p><p class="MsoNormal"><img alt="" class="left" height="314" src="../../../ib/chemistry/images/Practicals/Making esters.JPG" title="My students making esters - yes, I know they should have their safety glasses on!" width="235">Students need to know about weak acids and they should see that the solubility in water of organic acids such as benzoic acid increases dramatically when they are reacted with sodium hydroxide to form ionic salts. By deduction a similar effect is found when amines (which are weak bases) are reacted with acids to again form ionic salts. The chemistry of this is important for <a href="../19078/option-d-1.html" title="Options » Option D">Option D: Medicinal chemistry</a>. Many medicines (or illegal drugs) contain amine groups and are administered as their chloride salts - this is covered in more details in the page on <a href="../17377/salt-formation--1.html" title="New 2014 programme (First exams 2016) » Basic information » Resources » Novel uses for the IB data booklet » Salt formation ">salt formation </a> under <a href="../17348/novel-uses-for-the-ib-data-booklet--1.html" title="New 2014 programme (First exams 2016) » Basic information » Resources » Novel uses for the IB data booklet ">Novel uses for the IB data booklet</a>.

At SL students also need to be able to <span data-scayt-word="recognise" data-wsc-lang="en_US">recognise</span> the ester functional group and know the reaction between a carboxylic acid and an alcohol to make esters. It is fun for them to make an ester practically and smell the product (see right). After they have made ethyl <span data-scayt-word="ethanoate" data-wsc-lang="en_US">ethanoate</span> I get them to react a spatula full of salicylic acid (<span data-scayt-word="2-hydroxybenzoic" data-wsc-lang="en_US">2-hydroxybenzoic</span> acid) with a small amount of methanol in the same way (i.e. with a few drops of concentrated sulfuric acid acting as the catalyst). This will give them the very characteristic smell of methyl salicylate – which different cultures give different common names to. In the UK it is known as 'oil of wintergreen' and many students will <span data-scayt-word="recognise" data-wsc-lang="en_US">recognise</span> it as the smell of <span data-scayt-word="germolene" data-wsc-lang="en_US">germolene</span> or liniment to treat muscular pains</p><p>When they have finished the practical I briefly explain the chemistry behind the reactions. Then as we cover the chemistry in more detail in class I can refer back to these reactions and where necessary get them to write mechanisms as well as overall equations.</p><hr class="hidden"></div><hr class="hidden"><div class="box"><h2><img alt="Standard Level" class="ico" src="../../../img/icons/standard-1.png" title="Standard Level"> <img alt="Higher Level" class="ico" src="../../../img/icons/higher-1.png" title="Higher Level"> Student worksheet</h2><hr class="hidden"><p style="text-align: center;"><strong>REACTIONS OF ORGANIC COMPOUNDS</strong></p><hr class="hidden"><p>The aim of this practical is to compare and contrast the chemical properties and reactivities of some simple organic molecules containing different functional groups.</p><hr class="hidden"><p><strong>ENVIRONMENTAL CARE: </strong></p><p>After you have carried out the following reactions place any residues remaining in the container in the fume cupboard marked 'Organic Waste'. Do not pour organic waste down the sink.</p><hr class="hidden"><p><strong>SAFETY: </strong></p><p>Organic compounds tend to be highly inflammable. Keep them away from naked flames and keep the stoppers on the reagent bottles when not in use. Use only small quantities and use a water bath for heating. As much as possible avoid breathing in their fumes.</p><hr class="hidden"><p><strong>PROCEDURE:</strong></p><p><strong>1. Solubility.</strong> Generally only small polar molecules dissolve easily in water. Check this by adding a few drops of each of the following compounds to small quantities of cold water: cyclohexane, ethanol, <span data-scayt-word="butan-1-ol" data-wsc-lang="en_US">butan-1-ol</span>, <span data-scayt-word="octan-1-ol" data-wsc-lang="en_US">octan-1-ol</span>, <span data-scayt-word="propanone" data-wsc-lang="en_US">propanone</span> and cyclohexanone</p><p><strong>2. Reactivity of the hydrocarbons</strong>. Add a few drops of bromine solution to a few drops of each of the three hydrocarbons, cyclohexane, <span data-scayt-word="cyclohexene" data-wsc-lang="en_US">cyclohexene</span> and <span data-scayt-word="methylbenzene" data-wsc-lang="en_US">methylbenzene</span> (used instead of benzene) in small test-tubes. In the case of cyclohexane compare the effects of exposure to sunlight by placing one tube near the window and, to total darkness, by placing a second tube in the cupboard for the same length of time.</p><p><strong>3. Acidity and basicity</strong>. Most organic compounds are neutral in their response to a pH test. The following compounds are different.</p><p><strong>(a) </strong>Half fill four micro test tubes with distilled water. To the first add 4 drops of <span data-scayt-word="ethylamine" data-wsc-lang="en_US">ethylamine</span> solution, to the second 4 drops of phenylamine, to the third 4 drops of <span data-scayt-word="ethanoic" data-wsc-lang="en_US">ethanoic</span> acid and to the fourth a small amount of benzoic acid. Add 4 drops of universal indicator to each tube, mix and determine the pH by the <span data-scayt-word="colour" data-wsc-lang="en_US">colour</span> of the solution formed.</p><p><strong>(b)</strong> To 4 drops of phenylamine, add 10 drops of distilled water. Does it dissolve? Now add 5 or more drops of dilute hydrochloric acid and observe whether there is any tendency to dissolve.</p><p><strong>(c)</strong> To a small amount of benzoic acid, add 10 drops of distilled water. Does it dissolve? Now add 5 or more drops of dilute sodium hydroxide solution and observe what happens.</p><p><strong>4. Two reactions of ethanol</strong>.</p><p><strong>(a)</strong> <strong>Oxidation</strong>. Mix 10 drops of potassium dichromate(VI) solution with 10 drops of dilute sulfuric acid. Add 4 drops of this mixture to 5 drops of ethanol in a micro test tube and warm in a beaker of hot water. Observe any changes in <span data-scayt-word="colour" data-wsc-lang="en_US">colour</span> and smell.</p><p><strong>(b) Esterification</strong>. Mix 10 drops of ethanol with 10 drops of 'glacial' <span data-scayt-word="ethanoic" data-wsc-lang="en_US">ethanoic</span> acid and add 2 drops of concentrated sulfuric acid (care!). Warm the mixture in hot water for 5 minutes, then pour into 25 cm<sup>3</sup><sup> </sup>of dilute sodium carbonate solution. This removes the smell of any <span data-scayt-word="unreacted" data-wsc-lang="en_US">unreacted</span> <span data-scayt-word="ethanoic" data-wsc-lang="en_US">ethanoic</span> acid. Smell the product carefully and try to describe it.</p><hr class="hidden"><p><strong>QUESTIONS</strong></p><p><strong>1. </strong>Try to explain your observations giving relevant equations for any reactions taking place.</p><p><strong>2.</strong> Look up benzene on the chemistry HAZARD cards. Why was <span data-scayt-word="methylbenzene" data-wsc-lang="en_US">methylbenzene</span> used instead of benzene in experiment <strong>2</strong>? If benzene had been used how would you have expected it to react?</p><hr class="hidden"></div><hr class="hidden"><p>This worksheet can also be downloaded from:</p><p><a href="/media/ib/chemistry/files/2014%20practicals/Reactions-of-organic-compounds.pdf" target="_blank" title="Worksheets"><img class="ico" src="../../../img/icons/exercise-1.png"> <img alt="" height="16" src="../../../img/tib-icons/standard-level-24-1.png" title="" width="16"> <img alt="" height="16" src="../../../img/tib-icons/higher-level-24-1.png" title="" width="16"> Reactions of organic compounds</a></p></section></article><section id="media-extras"><div class="page-actions no-print navbar inline hidden-desktop"><div class="navbar-inner"><ul class="nav"><li><a class="presentation" href="#" onclick="return false;"><i class="fa fa-desktop"></i></a></li><li><a class="print-section-blog" href="#" onclick="return false;"><i class="fa fa-print"></i></a></li><li><a class="page-bookmarker" data-ticket="IB Docs (2) Team" data-pid="18598" href="#" onclick="return false;"><i class="fa fa-star"></i></a></li><li><a class="personal-notes" href="#" onclick="return false;"><i class="fa fa-file-text"></i></a></li><li><a class="" data-toggle="modal" href="#modal-feedback" onclick="return false;"><i class="fa fa-envelope-o"></i></a></li><li class="dropdown"><a class="dropdown-toggle" data-toggle="dropdown" data-target="#" href="#"><i class="fa fa-share-alt"></i></a><ul class="dropdown-menu" role="menu"><li><a class="" target="_blank" title="Share on Twitter" href="https://twitter.com/share?text=%22Reactions+of+organic+compounds%22+-+via+%40InThinker+%23chemistry%0A&url=https%3A%2F%2Fwww.thinkib.net%2Fchemistry%2Fpage%2F18598%2Freactions-of-organic-compounds"><i class="fa fa-twitter-square"></i><span>Twitter</span></a></li><li><a class="" target="_blank" title="Share on Facebook" href="https://www.facebook.com/sharer.php?u=https%3A%2F%2Fwww.thinkib.net%2Fchemistry%2Fpage%2F18598%2Freactions-of-organic-compounds&t=Reactions+of+organic+compounds"><i class="fa fa-facebook-square"></i><span>Facebook</span></a></li><li><a class="" href="http://www.linkedin.com/shareArticle?mini=true&url=https%3A%2F%2Fwww.thinkib.net%2Fchemistry%2Fpage%2F18598%2Freactions-of-organic-compounds"><i class="fa fa-linkedin-square"></i><span>LinkedIn</span></a></li><li><a class="" href="https://plus.google.com/share?url=https%3A%2F%2Fwww.thinkib.net%2Fchemistry%2Fpage%2F18598%2Freactions-of-organic-compounds"><i class="fa fa-google-plus-square"></i><span>Google +</span></a></li><li><a class="" href="mailto:?subject=Reactions of organic compounds&body=This is very much a practical introduction to organic chemistry and is excellent for demonstrating (or reinforcing) the underlying theory.
