Question

Nylon-$66$ is a polyamide obtained by the reaction of

• A. $COOH(CH_2)_4COOH + H_2NC_6H_4NH_2 - (p)$
• B. $COOH(CH_2)_4COOH + NH_2(CH_2)_6NH_2$
• C. $COOH(CH_2)_6COOH + NH_2(CH_2)_4NH_2$
• D. $COOHC_6H_4COOH - (p) + NH_2(CH_2)_6 NH_2$

Answer 1

Answer: (B)

The monomer units of nylon-$66$ are obtained by the reaction of hexamethylene diamine and adipic acid.
Nylon-$66$ contain polyamide bond and show condensation.
