Which of the following will yield a mixture of 2-chlorobutene and 3-chlorobutene on treatment with HCl?

Options

A. `CH_(2)=C=CH-CH_(3)`
B. `H_(2)C=underset(CH_(3))underset(|)C-CH=CH_(2)`
C. `CH_(2)=CH-CH=CH_(2)`
D. `HC-=C-CH=CH_(2)`

Answer

A

Explanation

`CH_(2)=C=CH-CH_(3)+H^(+)rarr`
`[CH_(2)=overset(+)C-CH_(2)CH_(3)+CH_(2)=CH-overset(+)CHCH_(3)]`
`overset(Cl^(-))rarrCH_(2)=underset("2-chlorobutene")underset(Cl)underset(|)C CH_(2)CH_(3)+CH_(2)=CH-underset("3-chlorobutene")underset(Cl)underset(|)CHCH_(3)`
