Which of the following (what)?
No, covalency does not have its own intermolecular force
Entropy
Ions combine in only one ratio, so prefixes are not needed.
A lone pair of electrons takes up space despite being very small. Lone pairs have a greater repulsive effect than bonding pairs. This is because there are already other forces needing to be taken into consideration with bond pairs.
So to summarize: Lone pair-lone pair repulsion > lone pair-bond pair repulsion > bond pair-bond pair repulsion. This makes the molecular geometry different.
The correct answer is: Bent.
The positive ionic radius is smaller than the neutral atomic radius
