Which of the following will most readily give the dehydrohalogenation product ?

Options

A.
B.
C.
D.

Answer

C

Explanation

Bromobenzene (a) cannot undergo dehydrohalogenation since it will produce benzyne which is a highly unstable species. 1-Bromocyclohexene (b) cannot undergo dehalogenation since it will produce a triple bond in a small cyclohexane ring. Both options (c ) and (d) can undergo dehydrohalogenation.

Thus, option (c ) is correct.
