Question

In which of the following pairs indicated, bond has less bond dissociation energy?

• A. I
• B. II
• C. Both are equal
• D. Cannot be determined

Answer 1

Answer: (A)

I

Bond I has less bond dissociation energy than bond II.
The extent of delocalization in bond I is lower than the extent of delocalization in bond II.
Thus, the strength of bond II is higher than the strength of bond I.
