Thermosetting polymer,


Thermosetting polymer, Bakelite is formed by the reaction of phenol with :-

  1. $\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CHO}$

  2. $\mathrm{CH}_{3} \mathrm{CHO}$

  3. $\mathrm{HCHO}$

  4. $\mathrm{HCOOH}$

Correct Option: , 3


Bakelite is a thermosetting polymer formed by the condensation reaction of phenol with $\mathrm{HCHO}$ in the presense of conc. $\mathrm{H}_{2} \mathrm{SO}_{4}$

It is thus, a cross-linked polymer in which condesation takes place at O- and p- positions So HCHO is the corerect option.
