Vedclass · Answer

(C) The reaction of a terminal alkyne with excess $HBr$ follows Markovnikov's rule. In the first step,$HBr$ adds across the triple bond to form a vinyl bromide intermediate: $Cyclohexyl-C\equiv CH + HBr \rightarrow Cyclohexyl-C(Br)=CH_2$. In the second step,another molecule of $HBr$ adds to the vinyl bromide,again following Markovnikov's rule,to form a geminal dibromide: $Cyclohexyl-C(Br)=CH_2 + HBr \rightarrow Cyclohexyl-C(Br)_2-CH_3$. Thus,the major product is $1,1-dibromo-1-cyclohexylethane$.
