Why can't Nitrogen (N) form five-coordinate compounds using hybridization?
Nitrogen lacks available d orbitals in its outermost shell.
Nitrogen is too large to accommodate five substituents without crowding.
Nitrogen has too many electrons in its outermost shell.
Nitrogen forms stable compounds with only four covalent bonds.
As there are no d-orbitals available in the Nitrogen valence shell, for which there is no way to arrange five pairs of bonding electrons around a nitrogen atom, and formation of five bonds.
