Vedclass · Answer

(C) In $SF_6$,the central sulfur atom $(S)$ undergoes excitation to form six covalent bonds with fluorine atoms.Ground state electronic configuration of $S$ is $[Ne] 3s^2 3p^4 3d^0$.To form $6$ bonds,$S$ promotes electrons from $3s$ and $3p$ orbitals to the empty $3d$ orbitals.This results in the $2^{nd}$ excited state configuration: $3s^1 3p^3 3d^2$.Since it has $6$ unpaired electrons,its covalency is $6$.The oxidation number of $S$ in $SF_6$ is calculated as: $x + 6(-1) = 0 \implies x = +6$.Thus,$S$ is in an excited state and its oxidation number is $+6$.
