Nitrogen has no d-orbital in its valence...

Nitrogen has no d-orbital in its valence shell and therefore it cannot

A

exhibit the oxidation state +5

B

have covalency greater than 3

C

exhibital hybridization

D

from oxides with oxidation state greater than +3

Text Solution

Verified by Experts

The correct Answer is:
B
Because of the absence of vacant d-orbitals electron excitation is not possible so it cannot have covalency greater than 3.

  • Sulphur and rest of the elements of group 16 are less electronegative than oxygen, Therefore, their atoms cannot take electrons easily. They can acquire ns^2 np^6 configuration by sharing two electrons with the atoms of other elements and thus, exhibit +2 oxidation state in their compounds. In addition to this, their atoms have vacant d-orbitals in their valence shell to which electrons can be promoted from the p and s-orbitals of the same shell. As a result, they can show +4 and + 6 oxidation states. Oxygen exhibits +2 oxidation state in

    A
    `H_2 O`
    B
    `OF_2`
    C
    `Cl_2 O`
    D
    `H_2 O_2`
