Topic 10 Organic chemistry  

10.1 Functional groups 
Picture
Identifying functional groups
Picture
Applications and skills: 
Identification of different classes: alkanes, alkenes, alkynes, halogenoalkanes, alcohols, ethers, aldehydes, ketones, esters, carboxylic acids, amines, amides, nitriles and arenes.
Identification of typical functional groups in molecules eg phenyl, hydroxyl, carbonyl, carboxyl, carboxamide, aldehyde, ester, ether, amine, nitrile, alkyl, alkenyl and alkynyl.
Guidance:
The distinction between class names and functional group names needs to be made. Eg for OH, hydroxyl is the functional group whereas alcohol is the class name.
It should be noted that the functional group in a ketone can also be referred to as a carbonyl function.

Guidance:
Reference should be made to initiation, propagation and termination steps in free-radical substitution reactions. Free radicals should be represented by a single dot.

Applications and skills:
Writing equations for the oxidation reactions of primary and secondary alcohols (using acidified potassium dichromate(VI) or potassium manganate(VII) as oxidizing agents). 
Explanation of distillation and reflux in the isolation of the aldehyde and carboxylic acid products.
The aldehyde can be distilled off because it has a lower boiling point than the alcohol or carboxylic acid (aldehydes do not form hydrogen bonds between molecules). If the aldehyde is left in contact with the oxidising agent, then the carboxylic acid is formed. An alternative oxidising agent is acidified potassium manganate(VII) solution which changes colour from purple to colourless.

10.2 Esterification/condensation reactions of alcohols and carboxylic acids 
Picture
Esters worksheet 
Understandings 
Alcohols undergo nucleophilic substitution reactions with acids (also called esterification or condensation)
Applications and skills:
Writing the equation for the condensation reaction of an alcohol with a carboxylic acid, in the presence of a catalyst (eg concentrated sulfuric acid) to form an ester.


10.2 Reactions of the halogenoalkanes 
Picture
Understandings:
Halogenoalkanes  are more reactive than alkanes. They can undergo (nucleophilic) substitution reactions. A nucleophile is an electron-rich species containing a lone pair that it donates to an electron-deficient  carbon.
Applications and skills:
Writing the equation for the substitution reactions of halogenoalkanes with aqueous sodium hydroxide.
Guidance:
The mechanisms of SN1 and SN2 and electrophilic substitution reactions are not required.
