• n-pentene

• 2-methylbut-2-ene

• but-2-ene

• 1-Chlorobutane

Answer 1

Addition of HCl to 2-methylbut-2-ene mainly gives 2-chloro-2-methylbutane.

Explanation:

\[\begin{array}{cc}
\phantom{...........................}\ce{Cl}\\
\phantom{...........................}|\\
\ce{CH3 - C = CH - CH3 + HCl -> CH3 - C - CH2 - CH3}\\
\phantom{}|\phantom{.................................}|\phantom{.......}\\
\phantom{..}\ce{\underset{2-Methylbut-2-ene}{CH3}\phantom{..................}\underset{2-Chloro-2-methylbutane}{CH3}}\phantom{...}
\end{array}\]
