Question

Among the following ions the p????–d???? overlap could be present in
(a) NO⁻₂ (b) NO⁻₃
(c) PO³⁻₄ (d)CO²⁻₃

Answer 1

Explanation:

c........I think. .............

Answer 2

The pπ - dπ overlap is present in (c) PO³⁻₄

Explanation:

• In phosphate, P = O bond has π bond. It is formed sideways which overlaps the d orbital of phosphorus and p orbital of oxygen.
• Thus, the pπ - dπ overlap in formed in phosphate.
• In NO⁻₂, NO⁻₃, CO²⁻₃, there is no vacant d orbital. Thus, the bond formed is pπ - pπ bond.
• There are three types of bonding which includes pπ - pπ, pπ - dπ and dπ - dπ.
