The structural formula of compound H is $\text{CH}_2{=}\text{CHCH}(\text{NH}_2)\text{COOH}$. State the functional groups present in H.
Compound H shows stereoisomerism. Draw the three-dimensional structures of the two stereoisomers of H, and name the type of stereoisomerism.
Compound H may be prepared by reacting J with an excess of hot aqueous acid. Complete Fig. 6.2 to show the equation for this reaction.
Name the reaction type in b(i).
Monomers can join together to form polymers by either addition or condensation polymerisation. Depending on the conditions, compound H can form addition polymer K or condensation polymer L. Draw one repeat unit of addition polymer K.
Draw two repeat units of condensation polymer L, and show the new functional group that is formed.
Explain why condensation polymers are usually able to biodegrade more readily than addition polymers.
Monomers join together to make polymers through either addition or condensation polymerisation. Under different conditions, compound H can produce addition polymer K or condensation polymer L.
