Thermosetting polymer bakelite is formed by the reaction of phenol with

Options

A ${CH}_{3} \cdot {CH}_{2} \cdot CHO$
B ${CH}_{3}. CHO$
C $H. CHO$
D $HCOOH$

Correct answer

C. $H. CHO$

Step-by-step solution

Bakelite is a thermosetting plastic which is formed by the reaction of phenol with $H. CHO$ in the presence of ${H}_{2}{SO}_{4}$ (conc).

The reaction occurs as follows:

Thermosetting polymer bakelite is formed by the reaction of phenol with

A cross-linked condensation polymer (at $o$ -and $p$ -position) bakelite is thus produced.
