Comment on nature of two S-O bond formed in `SO_2` molecule. Are the two S-O bonds in this molecule equal ?

Explanation

In `SO_(2)` molecule, S is `sp^(2)` hybridised. Two of three `sp^(2)` orbitals forms two o- bonds while third contains lone pair of electrons. S is left with one half filled p-orbital and one half filled d- orbital forming one p`pi`-p`pi` and one p`pi`-d`pi` double bond with oxygen atom. So `SO_(2)` has bent structure having OSO bond angle of 119.5° and.due to resonance both `pi`-bonds are equal (143 pm).
