Q17 / 90 · JEE Main 2021 (26 Aug Shift 1) · Chemistry

The polymer formed on heating Novolac with formaldehyde is:

A
Polyester
Correct answer
B
Bakelite
C
Nylon- $6, 6$
D
Melamine

Solution

Novolac on heating with formaldehyde undergoes cross-linking to form an infusible solid mass called Bakelite. It is a thermosetting polymer that cannot be reused or remoulded. Bakelite is used for making combs, phonograph records, electrical switches, and handles of various utensils

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