Question

In vsepr theory we dont consider double bonds. So why does the structure of SO2 have double bonds ?

Answer 1

Dear Student

In VSEPR theory, a double and triple bond are treated as a single bonding group. The sum of the number of atoms bonded to a central atom and the number of lone pairs formed by its non-bonding valence electrons is called steric number. The shape of molecules depend on steric number, atoms bonded to central atom and lone pairs.
The double bond of SO₂ is treated as single bond.
