If d represents the bond length, then select the correct relation.

Options

  1. Ad N 2   =   d N 2 +   and   d O 2 =   d O 2 +
  2. Bd N 2 <   d N 2 +   and   d O 2 > d O 2 +
  3. Cd N 2   <   d N 2 +   and   d O 2   <   d O 2 +
  4. Dd N 2   >   d N 2 +   and   d O 2   =   d O 2 +

Correct answer

B. d N 2 <   d N 2 +   and   d O 2 > d O 2 +

Step-by-step solution

Bond order ∝ 1/bond length. As bond order of N 2 = 3 , N 2 + = 2.5 As bond order of O 2 = 2 , O 2 + = 2.5 Here the correct order of bond length is d N 2 <   d N 2 +   and   d O 2   >   d O 2 +
