Multiple choice

Directions: In the question given below, there are two statements labelled Assertion (A) and Reason (R). Choose the correct option.

Assertion: The energy difference between staggered and eclipsed conformations of ethylene dichloride is less than in ethylene dibromide. Reason: The bond moment of C-Cl is greater than that of C-Br.

  1. Both A and R are true and R is the correct explanation of A.

  2. Both A and R are true, but R is not the correct explanation of A.

  3. A is true, but R is false.

  4. A is false, but R is true.

  5. Both A and R are false.

B Correct answer
Explanation

This option is correct. Due to steric hindrance between big-sized Br atoms, the energy difference between staggered and eclipsed forms of ethylene dibromide is more.
