IB syllabus for first examinations 2016

20.4 - Condensation reactions


20.4.1 :Describe, using equations, the reactions of alcohols with carboxylic acids to form esters and state the uses of esters. Mechanisms will not be assessed

 


20.4.2: The oxidation of primary, secondary and tertiary alcohols using acidified potassium dichromate(VI) solution.



20.4.1  

Describe, using equations, the reactions of alcohols with carboxylic acids to form esters and state the uses of esters.

Mechanisms will not be assessed

20.4.2  

Describe, using equations, the reactions of amines with carboxylic acids.

Mechanisms will not be assessed

20.4.3  

Deduce the structures of the polymers formed in the reactions of alcohols with carboxylic acids

Emphasise the need for two functional groups on each monomer. Include the polyester formed from ethane-1,2-diol and benzene-1,4-dicarboxylic acid. Include the identification of the repeating unit.

20.4.4  

Deduce the structures of the polymers formed in the reactions of amines with carboxylic acids.

Emphasise the need for two functional groups on each monomer. Include the polyamide formed from 1,6-diaminohexane and hexanedioic acid. Include the identification of the repeating unit.

20.4.5  

Outline the economic importance of condensation reactions.
