Question

Pentavalence in phosphorus is more stable when compared to that of nitrogen even though they belong to same group is due to :

• A. reactivity of phosphorus
• B. inert nature of nitrogen
• C. presence of d-orbital
• D. large size of phosphorus atom

Answer 1

Answer: (C)

presence of d-orbital

As vacant d-orbital are present in P so it can expand it valency and forms stable pentavalence product but due to absence of d-orbitals nitrogens pentavalence products are unstable.
