Correct answer: B

Electronic structure of S atom in excited state

AIPMT 2002 Chemistry - Chemical Bonding and Molecular Structure Question 55 English Explanation


In 'S' unhybride d- orbital is present, which will involved in bond formation with oxygen atom.

In oxygen two unpaired p- orbital is present in these one is involved in σ\sigma σ bond formation while other is used in π\pi π bond formation.

So, in SO32−-−, pπ\pi π −-− dπ\pi π bonding present.
