Q47. Maximum covalency of Nitrogen is: (a) 2 (b) 3 (c) 4 (d) 5

Nitrogen has a valence shell electron configuration of 2s²2p³. It can form three covalent bonds and can also form one dative (coordinate) bond using its lone pair of electrons (e.g., in ammonium ion, NH4+). Since nitrogen does not have vacant d-orbitals in its valence shell, it cannot expand its octet beyond 8 electrons. Therefore, the maximum covalency of nitrogen is 4.

What is the correct answer for CUET UG Chemistry Q47?

The correct answer is C. Nitrogen has a valence shell electron configuration of 2s²2p³. It can form three covalent bonds and can also form one dative (coordinate) bond using its lone pair of electrons (e.g., in ammonium ion, NH4+). Since nitrogen does not have vacant d-orbitals in its valence shell, it cannot expand its octet beyond 8 electrons. Therefore, the maximum covalency of nitrogen is 4.
