$CH_2Br - CBr = CH_2 \xrightarrow{Zn / CH_3OH}$

Vedclass · Answer

(A) The reaction $CH_2Br - CBr = CH_2 \xrightarrow{Zn / CH_3OH}$ is a debromination reaction. Zinc $(Zn)$ removes two bromine atoms from the adjacent carbons,leading to the formation of an allene structure. Specifically,$CH_2Br - CBr = CH_2 + Zn \rightarrow CH_2 = C = CH_2 + ZnBr_2$. Thus,option $A$ is the correct reaction to produce allene $(CH_2 = C = CH_2)$.

Which reaction will yield $CH_2 = C = CH_2$?
