To check whether the molecule is polar or not, we have to make a Lewis structure for the compound.
We will start by calculating the total number of valence electrons.
Group Valence e-
S 6A 1 x 6e- = 6e-
Cl 7A 4 x 7e- = 28e-
F 7A 2 x 7e- = 14e-
Total: 48 valence e-
Which statement best describes the polarity of SCl 4F2?
a. The molecule is always polar.
b. The molecule is always nonpolar.
c. Depending on the arrangement of outer atoms, this molecule could be polar or nonpolar.
