The energy of `sigma 2s` is greater than `sigma^("*")1s` Is orbital because

Options

A. `sigma 2s` is bigger than `sigma^(**)s` MO
B. `sigma 2s` is bonding whereas `sigma^(**)1s` is an ABMO
C. `sigma 2 s` orbital has a greater value of n than `sigma^(**)1s`MO
D. `sigma 2s` orbital is formed only after `sigma^(**) 1s`

Answer

C

Explanation

`sigma 2 s` orbital has a greater value of n than `sigma^(**)1s`MO
