Question

Nitrogen does not form $N{F}_5$ because :

• A. Nitrogen is member of V group
• B. It contain no empty d-orbital
• C. The bond energy of $N\equiv N$ is very high
• D. Inert pair effect exists in the molecules

Answer 1

The correct option is B It contain no empty d-orbital

$N{F}_5$ does not exists as there are 10 electrons, and N does not have vacant d-orbitals to accomodate the extra electrons.
