"Less than" Degrees (HW)

Postby Qilan Li 4I » Thu Nov 14, 2019 11:47 pm

On homework questions, 2E.5, 2E.7, and 2E.9, the answers to the bond angles are all "less than blank." Is this because they all have lone pairs that push the bonded pairs together creating a "less than" degree. Why is that? Does this "less than" degree occur between only the bonded pairs or all groups of electrons around the central atom?

I think this is because in order for the molecule to be in the most "stable" state, the lone pairs and attached atoms need to be as far apart as possible, and the lone pairs cause the angles to decrease.
