Q. Thermosetting polymer,Bakelite is formed by the reaction of phenol with
A) ${CH}_{3}{CH}_{2}CHO$
B) ${CH}_{3}CHO$
C) $HCHO$
D) $HCOOH$
Explanation
(c)
Bakelite is a thermosetting plastic formed by reaction of phenol with HCHOin the presence of conc.$H_{2}SO_{4}$.

It is thus cross-linked polymer,condensation taking place at o- and p- positions.
Thus, HCHO.
