What is hybridization of s in so2?

Answer 1

You have to determine the Lewis structures of both before you can answer this:

Sulfur has 6 valence electrons and so does oxygen, so in SO2, we're dealing with 18 valence electrons total. First, draw single bonds between the S and each O, then fill out an octet for each O. This uses 16 electrons. The other two should be placed as a lone pair on the S. Finally, move a lone pair on one of the O's so that it forms a second bond with the S. This completes an octet for all atoms. Now count electrons groups around the S: there's a double bond, a single bond, and a lone pair.... that makes 3. So the S in SO2 is sp2 hybridized

Answer 2

The sulfur atom in SO2 undergoes sp2 hybridization. This means that the sulfur atom uses one 2s orbital and two 2p orbitals to form three sp2 hybrid orbitals, which are then involved in bonding with the oxygen atoms in the molecule.
