Arrange the following species in the decreasing order of their bond orders:

Options

  1. A(I) > (II) > (III)
  2. B(II) > (I) > (III)
  3. C(II) > (III) > (I)
  4. D(III) > (II) > (I)

Correct answer

B. (II) > (I) > (III)

Step-by-step solution

( The strength of bond is determined by bond order (BO). Number of electrons in bonding molecular orbital (a) - Number of electrons in BO = antibonding molecular orbital (b) 2
