Vedclass · Answer

(D) The reaction of an alkyne with excess $Br_2$ in $CCl_4$ is an electrophilic addition reaction. During this process,both $\pi$-bonds of the triple bond are broken,and four new $\sigma$-bonds are formed with bromine atoms. For hex$-1-$yne $(CH_3(CH_2)_3C \equiv CH)$,the addition occurs at the $C-1$ and $C-2$ positions. The final product is $1,1,2,2-$tetrabromohexane. $CH_3(CH_2)_3C \equiv CH + 2Br_2 \xrightarrow{CCl_4} CH_3(CH_2)_3C(Br)_2-CH(Br)_2$
