$CH_3-C(Cl)=C(Cl)-CH_2CH_3$ (anti-addition product)

Vedclass · Answer

(A) The reaction of an alkyne with $1 \ mol$ of $Cl_2$ is an electrophilic addition reaction. The addition of halogens to alkynes typically proceeds via an anti-addition mechanism,resulting in the formation of a trans-dihaloalkene as the major product. The reaction is: $CH_3-C \equiv C-CH_2-CH_3 + Cl_2 \rightarrow CH_3-C(Cl)=C(Cl)-CH_2CH_3$ (trans-isomer).

What is the major product of the following reaction? $CH_3-C \equiv C-CH_2-CH_3 \xrightarrow{1 \ mol \ of \ Cl_2} \text{?}$
