Vedclass · Answer

(A) The reaction of propyne $(CH_3-C\equiv CH)$ with two moles of $HBr$ follows Markovnikov's rule.In the first step,$HBr$ adds to the triple bond to form $2$-bromopropene $(CH_3-C(Br)=CH_2)$.In the second step,another molecule of $HBr$ adds to the double bond of $2$-bromopropene,again following Markovnikov's rule,to form $2, 2$-dibromopropane $(CH_3-C(Br)_2-CH_3)$.
