Title: Bonding in sulphur dioxide
Post by: AdityaDev on July 14, 2015, 11:34:22 PM

Why is there a pπ-dπ overlap in SO₂?
Why not a pπ-pπ overlap?
How do you find out if the d orbital is involved in π-bonds?
I know that pπ-dπ is effective when the size of d orbital is similar to size of p orbital and secondly, the size of d orbital decreases from Phosphorous to Chlorine.

Check wikipedia for sulfur dioxide (and ref. 6)

But it does not explain why d orbital participates in π bond.

They practically do not participate
