Bond energies in `NO,NO^(+)` and `NO^(-)` are such as

Options

A. `NO^(+) gt NO gt NO^(-)`
B. `NO gt NO^(+) gt NO^(-)`
C. `NO^(-) gt NO gt NO^(+)`
D. `NO^(+ ) gt NO^(-) gt NO`

Answer

a

Explanation

B.O. In ` NO= (1)/(2) (10-5) = 2.5`
B.O. in ` NO^(+) = (1)/(2) (10 -4) = 3.0`
B.O. in ` NO^(-) = (1)/(2) (10 - 6) = 2.0`
Since the bond energies are directly related to bond
order . Therefore , the correct order of increasing bond
energies is ` NO^(+) gt NO gt NO^(-)` .
