The number of nodal planes present in \[{{\sigma }^{*}}s\] anti bonding orbitals is

A)  1                                            

B)  2

C)  0                                            

D)  3

Correct Answer: A

Solution :

In an anti-bonding molecular orbital, most of the electron density is located away from the space between the nuclei, as a result of which there is a nodal plane {ie, a plane at which the electron density is zero) between the nuclei.
