Question

Which of following bonds has maximum bond length?

Options

• C - O

• C - H

• C - C

• C - N

Answer 1

C - H

Explanation:

Because the electronegativities of C - H bonds are less different than those of C - O, C - C, and C - N bonds.

As a result, the C - H bond has less polarity and so has the longest bond length.
