During change of `NO^(+)to NO`, the electron is added to

Options

A. `sigma`-orbital
B. `pi`-orbital
C. `sigma^(**)`- orbital
D. `pi^(**)-` orbital

Answer

D

Explanation

M.O configuration of `NO^(+)` is :
`(sigma1s)^(2)(sigma^(* *)1s)^(2),(sigma^(* *)2s)^(2) (sigma2p_(z))^(2) (pi2p_(x))^(2) (pi2p_(y))^(2)` and M.O configuration of NO is :
`(sigma1s)^(2)(sigma* *1s)^(2) (sigma2s)^(2) (sigma* *2s)^(2) (sigma 2p_(z))^(2) (pi2p_(x))^(2) (pi 2p_(y))^(2) (pi^( * *) 2p_(x))^(1)`
