Options

  1. ACH 3 · CH 2 · CHO
  2. BCH 3 . CHO
  3. CH . CHO
  4. DHCOOH

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