Two pi and half sigma bonds are present in :

Multiple Choice Options

  • A O2
  • B N2+
  • C O2+
  • D N2

Step-by-Step Verified Solution

Two pi and half sigma bonds are presents in molecule with bond order 2.5.

Moleculer orbital configuration of N2+ (13 electrons)

= σ1s2σ1s2∗σ2s2σ2s2∗π2px2=π2py2σ2pz1

Bond order = 12(9−4) = 2.5
