Which of the following will yield a mixture of 2-chloro butene and 3-chloro butene on treatment with HCl?
(1) \(CH_2 = C = CH - CH_3\)
(2) \(H_2C-\underset{CH_3}{\underset{|}{C}} = CH - CH_2\)
(3) \(CH_2 = CH - CH = CH_2\)
(4) \(HC ≡ C - CH =CH_2\)

Correct answer: (1) \(CH_2=C=CH-CH_3\)
Explanation:
\(CH_2=C=CH-CH_3\overset{H^+}\longrightarrow\) \(\Big[CH_2=C^+ - CH_2 - CH_3 + \)\(CH_2 = CH - CH^+ - CH_3\Big]\) \(\overset{Cl^-}\longrightarrow\) \(CH_2= \underset{Cl}{\underset{|}C}-CH_2CH_3+CH_2\)\(=CH - \underset{Cl}{\underset{|}C}HCH_3\)
