Question

Assertion :For $C_2{H}_6$ staggered conformation is more stable than eclipsed. Reason: In staggered conformation, the bonded electrons have minimum repulsions.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion

Staggered conformation - arrangement of carbon and hydrogen at the maximum distance that needed a torsion angle ${60}^O$.

Eclipsed conformation - arrangement of carbon and hydrogen at the minimum distance that requires torsion angle $0^O$.

A compound has higher potential energy those have less torsion angle and a compound are less stable that has higher potential energy.

Hence, option B is the correct answer.
