Question

Which of the following isomer of 1, 2-cyclohexanedicarboxylic acid forms an hydride on heating?

Choose the correct answer from the options given below:

• A. (B) and (C) only.
• B. (A). (B) and (C) only
• C. (A). (C) and (D) only
• D. (B), (C) and (D) only

Hint:

The formation of anhydrides from dicarboxylic acids is favored by heating and occurs via intramolecular condensation.

Answer 1

The Correct Option is B

The heating of Isomer 2 of 1, 2-cyclohexanedicarboxylic acid undergoes intramolecular dehydration, leading to anhydride formation.
