Vedclass · Answer

(D) Oxygen $(O)$ belongs to the second period and has an electronic configuration of $[He] 2s^2 2p^4$. It lacks vacant $d$-orbitals in its valence shell,which prevents it from expanding its octet. Therefore,it cannot form compounds like $OF_4$ or $OF_6$ where the central atom would require more than eight electrons in its valence shell.
