Multiple choice

Which of the following order of bond energy is correct ?

  1. N2 > N2+ = N2- .

  2. N2 < N2+ = N2- .

  3. N2 > N2+ > N2- .

  4. N2 > N2+ < N2- .

C Correct answer
Explanation

This option is correct. Bond order of N2 = 3. Bond order of N2+ = 2.5. Bond order of N2- = 2.5. Since bond order of N2+ and N2- is the same, but the effective nuclear charge of N2+ is more than that of N2-, so the correct order is N2 > N2+ > N2-.
