Vedclass · Answer

(C) The reaction of an alkyne with excess $HBr$ proceeds via electrophilic addition. First,$HBr$ adds to the triple bond to form a vinyl bromide intermediate. Since $HBr$ is in excess,a second molecule of $HBr$ adds to the same carbon atom (following Markovnikov's rule) to form a geminal dibromide. Thus,the reaction of cyclohexylacetylene with excess $HBr$ yields $1,1$-dibromo-$1$-cyclohexylethane.
