Multiple choice

What is the expected order of bond energy of the following bong types? O-O, S-S, C-N, S-H, C=C, C=N, C=O

  1. O-O < S-S < C-N < S-H < C=C = C=N < C=O

  2. S-S < O-O < C-N < S-H < C=C = C=O < C=N

  3. C-N < S-S < O-O< S-H < C=C < C=N = C=O

  4. S-S < O-O < C-N < S-H < C=C < C=N < C=O

  5. O-O < S-S < C-N < S-H < C=N < C=C < C=O
