Q3 / 90 · JEE Main 2019 (12 Jan Shift 2) · Chemistry

The two monomers for the synthesis of nylon $6, 6$ are

A
$HOOH {({CH}_{2})}_{4} COOH, H_{2} N {({CH}_{2})}_{4} {NH}_{2}$
Correct answer
B
$HOOC {({CH}_{2})}_{4} COOH, H_{2} N {({CH}_{2})}_{6} {NH}_{2}$
C
$HOOC {({CH}_{2})}_{6} COOH, H_{2} N {({CH}_{2})}_{4} {NH}_{2}$
D
$HOOC {({CH}_{2})}_{6} COOH, H_{2} N {({CH}_{2})}_{6} {NH}_{2}$

Solution

Nylon $6, 6$ is made up of hexamethylenediamine $(H_{2} N {({CH}_{2})}_{6} {NH}_{2})$ and adipic acid $(HCOO - {({CH}_{2})}_{4} - COOH) .$

${NH}_{2} {({CH}_{2})}_{6} {NH}_{2} + HCOO {({CH}_{2})}_{4} COOH$

Hence, the correct answer is option: 'B'.
