Question

Which of the following bonds require the largest amount of bond energy to dissociate the atoms concerned ?
A. H-H bond in `H_2`
B. C-H bond in `CH_4`
C. N = N bond in `N_2`
D. O=O bond in `O_2`

Answer 1

Correct Answer - C
Out of the given five choices, `N-= N` bond has highest B.E. (943 J `mol^(-1)`). B.E of H-H bond is 433 kJ `mol^(-1)`.
