Vedclass · Answer

(C) The dimerization of acetylene $(HC \equiv CH)$ in the presence of a catalyst system consisting of cuprous chloride $(Cu_2Cl_2)$ and ammonium chloride $(NH_4Cl)$ yields vinyl acetylene $(HC \equiv C-CH=CH_2)$.This vinyl acetylene then reacts with hydrogen chloride $(HCl)$ to form $4$-chloro-$1,2$-butadiene,which subsequently rearranges to form $2$-chloro-$1,3$-butadiene,commonly known as chloroprene.

The catalyst used in the dimerization of acetylene to prepare chloroprene is:
