Problem: 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.

FREE Expert Solution

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.

SCl4F2
                        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-
