Final answer:
SF₃Cl₂ is a polar molecule due to the difference in electronegativities between the fluorine and chlorine atoms.
Step-by-step explanation:
The molecule SF₃Cl₂ is polar. To determine if a molecule is polar or nonpolar, we look at its molecular geometry and the electronegativities of its atoms. In SF₃Cl₂, the sulfur atom is the central atom and there are three fluorine atoms and two chlorine atoms bonded to it.
The molecule has a trigonal bipyramidal shape, with the three fluorine atoms in the equatorial position and the two chlorine atoms in the axial position. The fluorine and chlorine atoms have different electronegativities, causing a difference in the distribution of electron density and resulting in a polar molecule.
