MCQ
Nitrogen differs from $\text{P, As, Sb}$ and $Bi$ in the following properties:
  • A
    It forms diatomic molecule.
  • B
    It is not able to extent its coordination number beyond four.
  • C
    Nitrogen does not function as a Lewis acid whereas $\text{P, As, Sb}$ and $Bi$ do so.
  • ✓
    In all the properties given above.
✓

Answer

Correct option: D.
In all the properties given above.
As vacant $d-$orbital are present in $P$ and other elements of this group except $N$ so they can expand their valency and forms stable pentavalence product but due to absence of $d-$orbitals nitrogen cannot form pentavalence products. It forms diatomic molecule $N_2$
Nitrogen does not function as a Lewis acid due to absence of $d-$orbitals and it is a Lewis base due to presence of lone pair.
