Q.
The number of nodal planes present in $\sigma^{*} 2s$ anti- bonding orbital is.
Chemical Bonding and Molecular Structure
Solution:
In the 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 (i.e., a plane at which the electron density is zero) between the nuclei. The number of nodal planes present in $\sigma^{*} 2s$ anti-bonding orbitals is $1.$
