Vedclass · Answer

(B) The reaction of propyne $(CH_3-C \equiv CH)$ with two equivalents of $HBr$ follows Markovnikov's rule.In the first step,$H^+$ adds to the terminal carbon and $Br^-$ to the middle carbon to form $2-$bromopropene $(CH_3-C(Br)=CH_2)$.In the second step,another $HBr$ adds following the same rule to form $2, 2-$dibromopropane $(CH_3-C(Br)_2-CH_3)$.Reaction:$CH_3-C \equiv CH + HBr$ $\rightarrow CH_3-C(Br)=CH_2$ $\xrightarrow{HBr} CH_3-C(Br)_2-CH_3$

Which of the following reactions will yield $2, 2-$dibromopropane?
