Vedclass · Answer

(D) The electronic configuration of nitrogen $(Z=7)$ is $1s^2, 2s^2, 2p^3$.Nitrogen belongs to the second period and lacks $d$-orbitals in its valence shell.Because of the absence of vacant $d$-orbitals,nitrogen cannot expand its octet to form pentahalides (like $NF_5$).Other elements of group $15$ (like $P, As, Sb$) possess vacant $d$-orbitals,allowing them to exhibit a higher covalency of $5$ and form pentahalides.

In group $15$ of the periodic table,nitrogen forms only a trihalide,but other elements form pentahalides also. The reason is:
