Question

Which is most easily dehydrohalogenated?

• A.

  

• B.

  

• C.

  

• D. Both A and B

Answer 1

The correct option is A

Explanation for the correct option

(A)

• This compound is resonance stabilized
• Thus, dehydrohalogenation becomes relatively simple when a stable product is produced.

Explanation for the incorrect options

(B)

• In this compound, no stable product is formed after dehydrohalogenation.

(C)

• It is very unstable due to sp² hybridized.
• Its electronegativity is too high.

Hence, options (B), (C), and (D) are incorrect.

Hence, option (A) is correct. The compound given in option (A) is most easily dehydrohalogenated.
