Answer:
B) Although this site is not desirable for making a bond between atoms, it is a good site in the sense that the electrons can be close to the nucleus.
Explanation:
An antibonding orbital points away from the nuclei, with a node between them, so the electrons are not held close to the nuclei. The orbital is not desirable for bonding.
The diagram below shows a σ*1s molecular orbital, but a σ*2s orbital has a similar shape.
A) is true. The σ*1s orbital has the lowest energy.
C) is true. Any orbital can accommodate at most one electron pair.
D) is may be true. Orbital energy decreases as atomic number increases, so the orbital energy of an N₂ σ*2s molecule may be close to that of a sulfur atom's 2s orbital.
