The monomer of $Nylon-6$ is Terylene.

Vedclass · Answer

(D) $1$. $Nylon-6$ is formed by the polymerization of caprolactam,so statement $A$ is correct.$2$. Natural rubber is a polymer of isoprene $(2-methyl-1,3-butadiene)$,so statement $B$ is correct (Note: The original option $B$ mentioned butadiene,which is technically incorrect as natural rubber is polyisoprene,but statement $D$ is explicitly false as Terylene is a polyester,not a monomer of $Nylon-6$).$3$. Phenol-formaldehyde resin is indeed known as Bakelite,so statement $C$ is correct.$4$. $Nylon-6$ is a polyamide,while Terylene is a polyester. Thus,statement $D$ is incorrect.
