Lone pairs of other atoms in molecule

Postby DesireBrown1J » Wed Nov 13, 2019 6:00 pm

Do the lone pairs of the noncentral/surrounding atoms affect the shape and angles of the overall molecule? If so, how do they change the shape?

The lone pairs only affect the shape if they are on the central atom. Lone pairs on the surrounding atoms have no effect on the shape of the molecule.

VSEPR models center around the electrons/electron pairs of the central atom.

I'm confused on the bond angle for T-shaped molecules with 2 lone pairs (and 3 bonding pairs)? Is it all less than 90?
Thanks!
