Solution

## The correct option is C ${\mathrm{OF}}_{4}$Explanation for correct option:C. ${\mathrm{OF}}_{4}$This molecule does not exist theoretically.In ${\mathrm{OF}}_{4}$, Oxygen exhibits the valency of $4$ which is not possible as the valency of Oxygen is $2$.Explanation for incorrect options:A. ${\mathrm{SF}}_{4}$${\mathrm{SF}}_{4}$ exist as trigonal bipyramidal shape.It is a polar molecule.B. ${\mathrm{OF}}_{2}$ Oxygen difluoride is a chemical compound with a chemical formula ${\mathrm{OF}}_{2}$.As predicted by VSEPR theory, the molecule adopts a "bent" molecular geometry.C. ${\mathrm{O}}_{2}{\mathrm{F}}_{2}$Dioxygen difluoride is a compound of fluorine and oxygen with the molecular formula ${\mathrm{O}}_{2}{\mathrm{F}}_{2}$.Hence, the correct option is C i.e. ${\mathrm{OF}}_{4}$ does not exist theoretically.
