Vedclass · Answer

(A) $1$. Reaction of $1,2-	ext{dibromopropane}$ with $Zn$ and $\Delta$ (dehalogenation) yields $C = 	ext{propene}$ $(CH_3-CH=CH_2)$.$2$. Reaction of $1,2-	ext{dibromopropane}$ with $(i)$ $	ext{alc. } KOH$ and (ii) $NaNH_2$ (dehydrohalogenation) yields $A = 	ext{propyne}$ $(CH_3-C \equiv CH)$.$3$. Hydrogenation of $A$ $(	ext{propyne})$ using $	ext{Lindlar catalyst}$ yields $B = 	ext{propene}$ $(CH_3-CH=CH_2)$.$4$. Thus,$B$ is $	ext{propene}$ and $C$ is $	ext{propene}$.

What are $B$ and $C$ respectively in the following set of reactions?
$C \xleftarrow[\Delta]{Zn} 1,2-\text{dibromopropane}$ $\xrightarrow[\text {(ii) } NaNH_2]{\text {(i) alc. } KOH} A$ $\xrightarrow[\text { Catalyst }]{\text { Lindlar }} B$
