Vedclass · Answer

(A) Bakelite is a thermosetting polymer formed by the condensation polymerization of phenol and formaldehyde (methanal). In this reaction,phenol reacts with methanal $(HCHO)$ in the presence of an acid or base catalyst to produce a cross-linked polymer structure. Therefore,methanal is one of the essential monomers used in the synthesis of bakelite.
