Answer:
The Bond order of NO⁺ (x) is 3 and bond order of NO⁻ (y) is equal to 2.
The value of (x+y) is equal to 5.
Explanation:
From the energy level diagram of molecular orbitals of NO, the electron distribution will be as:
During the formation of NO⁺, one electron is removed from NO:
Bond order
Therefore, Bond order of NO⁺
Now, During the formation of NO⁻, one electron added in NO:
Bond order of NO⁻
Now, bond order of NO⁺,
Bond order of NO⁻ ,
So,
Therefore, the value of (x + y) is equal to 5.
