bond angles

Postby Lea Ozdere 2G » Sat Dec 12, 2020 10:04 pm

Just to confirm, for VSEPR theory for any molecules with one or more lone pairs, we just need to know that the bond angles for those will be less than the ones with no lone pairs which we know the angles of, right? We don't have to know the specific angles for ones with 1 or more lone pairs?

No, saying slightly less than or less than is sufficient.

He would not test on specific angles, but I think ranking the bond angles of bent, trigonal pyramidal, and tetrahedral would be fair game, for example. As long as you understand that more lone pairs lead to increased repulsion and smaller bond angles, you should be all good!

Yes, you can just say less than or slightly less than to indicate the bond angles. I don't think we are expected to know exactly the angles of the bonds in the presence of lone pairs.
