Chemistry Question on Polymers

Nylon-66 is a polyamide obtained by the reaction of

A

COOH(CH2)4COOH+H2NC6H4NH2−(p)COOH(CH_2)_4COOH + H_2NC_6H_4NH_2 - (p)

B

COOH(CH2)4COOH+NH2(CH2)6NH2COOH(CH_2)_4COOH + NH_2(CH_2)_6NH_2

C

COOH(CH2)6COOH+NH2(CH2)4NH2COOH(CH_2)_6COOH + NH_2(CH_2)_4NH_2

D

COOHC6H4COOH−(p)+NH2(CH2)6NH2COOHC_6H_4COOH - (p) + NH_2(CH_2)_6 NH_2

Answer

COOH(CH2)4COOH+NH2(CH2)6NH2COOH(CH_2)_4COOH + NH_2(CH_2)_6NH_2

Explanation

Solution

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.
