Vedclass · Answer

(B) The addition of $HCl$ to $2$-methylpropene follows Markovnikov's rule,where the $Cl^-$ attaches to the more substituted carbon atom.$CH_3-C(CH_3)=CH_2 + HCl \rightarrow CH_3-CCl(CH_3)-CH_3$The addition of $HCl$ to ethyne follows Markovnikov's rule in the second step,leading to the formation of a geminal dihalide.$CH \equiv CH + HCl$ $\rightarrow CH_2=CHCl$ $\xrightarrow{HCl} CH_3-CHCl_2$Thus,the products are $CH_3-CCl(CH_3)-CH_3$ and $CH_3-CHCl_2$.

Action of hydrogen chloride on $CH_3-C(CH_3)=CH_2$ and on $CH \equiv CH$ will predominantly give the compounds,respectively:
