In which of the following p -d bonding is possible?
Options
- ACO ₃ ²⁻
- BPO ₄ ³⁻
- CNO ₃⁻
- DNO ₂⁻
Correct answer
B. PO ₄ ³⁻
Step-by-step solution
Carbon, oxygen and nitrogen atoms do not have any d -orbital available. Therefore, in CO ₃²⁻, NO ₂⁻ and NO ₃⁻ , there is no possibility of p -d type of bonding. In PO ₄ ³⁻ phosphorus atom has vacant d -orbital available which is used to form p -d type of bonding with p -orbital of oxygen atom.
