Answer: a
Explanation: The repulsive interactions follow the above order. The lone pairs are
localized on the central atom, each bonded pair is shared between two atoms. So, the
lone pair electrons in a molecule occupy more space as compared to the bonding pairs
of electrons.
2. The shape of the molecule depends on the _______
3. The shape a molecule occupies allows to minimize repulsions among them and
maximize the space between them.
