Question

which of the following contains p-pi d-pi bond

Answer 1

Answer:

In SO

3

2−

ion, the sp

3

is hybridised, so

In S the, three p-orbitals forms a bonds with three oxygen atoms and unhybridised & orbital is involved in it bond formation.

In oxygen, two unpaired. p-orbitals are present, one is involved in σ-bond formation while other is used in π-bond formation.

Thus, in SO
