Vedclass · Answer

(B) Fluorine is the most electronegative element and has the smallest size among halogens. Crucially,it lacks $d$-orbitals in its valence shell $(n=2)$. Due to the absence of vacant $d$-orbitals,it cannot expand its octet or promote electrons to higher energy levels to exhibit positive oxidation states like $+3, +5,$ or $+7$. Therefore,it only shows a $-1$ oxidation state.

Unlike other halogens,fluorine does not show higher oxidation states because:
