Question

The manufacture of nylon-6 involves condensation of
(a) Phenol and formaldehyde
(b) Urea and formaldehyde
(c) Adipic acid and hexamethylene diamine
(d) Ethylene glycol and pthalic acid

Answer 1

Answer:c

Explanation:

Answer 2

The manufacture of nylon-6,6 involves condensation of (c) Adipic acid and Hexamethylene diamine.

• Nylon 6,6 is the first artificial polyamide.
• Its chemical name is name is polyhexamethylene adipamide.
• It is produced by condensation polymerisation of adipic acid [HOOC-(CH$_2$)$_4$-COOH] and hexamethylene diamine [H$_2$N-(CH$_2$)$_6$-NH$_2$]. So  it is a copolymer.

• Nylon 6,6 is used in preparing brushes, ropes, mosquito nets etc.
