Vedclass · Answer

(A) The reaction between phenol and formaldehyde to form Bakelite is a step-growth polymerization process. The initial step involves the electrophilic attack of formaldehyde (in the presence of an acid or base catalyst) on the ortho or para positions of the phenol ring. Since the phenol ring is electron-rich,it undergoes $Aromatic \ electrophilic \ substitution$ to form ortho-hydroxybenzyl alcohol or para-hydroxybenzyl alcohol.

Bakelite is formed by the reaction between phenol and formaldehyde. The initial reaction between these two compounds is an example of ..............
