Which statement describes the vsepr theory?

a- electron pairs in the valence shell of an atom have a tendency to attract other nearby electron pairs.

b- electrons in the valence shell of an atom exert a repulsive force on other atoms while forming a chemical bond.

c- electron pairs in the valence shell of an atom exert a repulsive force on all other electron pairs in the valence shell of the atom.

d- electrons in the valence shell exert a repulsive force while completing their octet during the formation of chemical bond.

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.

stupid i wont let you get a chance
