Polymers — practice question

Molecules A and B are able to make condensation polymers.
(a(i))[1]

Name the functional group found in B.

(a(ii))[3]

Draw the section of the synthetic polymer produced when two molecules of A and two molecules of B join together. Make sure every bond in the linkages is shown.

(a(iii))[1]

Name the additional product made when molecules of A and B polymerise.

(b(i))[1]

Draw the section of the complex carbohydrate that could be hydrolysed to produce molecules of A. Include one linkage and display every bond in that linkage.

(b(ii))[2]

State two sets of conditions that could be used to hydrolyse the complex carbohydrate and produce A.

(b(iii))[1]

Name the technique used to identify the individual sugar units produced by hydrolysis of a complex carbohydrate.

(c(i))[1]

State what this process is called.

(c(ii))[2]
