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

A)  \[1\]              

B)  \[2\]

C)  \[0\]               

D)  \[3\]

Correct Answer: A

Solution :

In an antibonding 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 (i.e., a plane at which the electron density is zero) between the nuclei.
