The formation of which of the following polymers involves hydrolysis reaction?

(A)Nylon 6✓ Correct
(B)Bakelite
(C)Nylon 6, 6
(D)Terylene

Answer: (A)

Solution

Nylon-6 is built by ring-opening of caprolactam, and that opening goes through hydrolysis of the lactam to the amino acid

H X_{2} N - (CH X_{2}) X_{5} - COOH

before polymerisation sets in. Bakelite, Nylon-6,6 and Terylene all form by straightforward condensation with no hydrolysis step, so it is Nylon-6 whose formation involves a hydrolysis.
