What Orbitals Are Involved in Bond Formation for Common Molecules and Ions?

[Soaring Crane]

For the following molecules and ions, indicate the obitals involved in bond formation.


1) SO2
The central atom is S, and it has 1 double bond with a O and a single bond with the remaining O. There is also 1 lone electron pair. Therefore, a S-O bond is sp^2-p while a S=O bond is sp^2-sp^3?


2) NO3-
N is central atom, and there are 2 single bonds between 2 O atoms and a double bond between the other O. A N-O bond is sp^2-p while a N=O bond is sp^2-sp^3?


3) NO2+
N is central atom, and there are 2 double bonds between both O atoms and N. Thus, a N=O bond is sp-sp^3?


4) NO2-
There is 1 single bond between a O atom and N and 1 double bond with the other O. One lone e- pair exists for N. A N-O bond is sp^2-p and a N=O bond is sp^2-sp^3?

Thanks.
