5 bonding, 1 non-bonding, molecular geometry?

A

square pyramidal

22
Q

4 bonding, 2 non-bonding, molecular geometry?

A

square planar

23
Q

which molecules can have expanded octets?

A

those with a central atom in period 3 or below

24
Q

why can expanded octets exist?

A

d-orbitals and p-orbitals are close in energy so p-orbital electrons can be promoted to allow for additional bonding electrons
