Which one of the following pairs of species have the same bond order?
CO, NO
O2, NO+
CN-, CO
Bond Order -
Bond order is defined as one half the difference between the number of electrons present in the bonding and the antibonding orbitals.
- wherein
Bond order = 1/2(Nb - Na).
O2 : N b = 10, N a = 6, Bond order = 2
NO+ : N b = 10, N a = 4, Bond order = 3
CN- : N b = 10, Na = 4, Bond order = 3
CO : N b = 10, Na = 4, Bond order = 3
N2 : N b = 10, Na = 4, Bond order = 3
O-2 : N b = 10, Na = 7, Bond order = 1.5
NO : N b = 10, Na = 5, Bond order = 2.5
Option 1)
CO, NO
this is the incorrect option
Option 2)
O2, NO+
this is the incorrect option
Option 3)
CN-, CO
this is the correct option
Option 4)
this is the incorrect option
