Which of the following has the lowest number of unshared electrons around the central atom?

Question

a) XeF4
b) SO2
c) ClF3
d) H2O
e) SF6

I put SO2 as my answer and the correct answer that showed up was SF6. I don't understand how SF6 is correct, when all the electrons are paired around the central atom? Can someone explain, I'm confused.

Answer 1

Yes. The question is NOT how many electrons are paired or unpaird. The question is how many electrons are unshared.
XeF4 has 4
SO2 has 2
ClF3 has 4
H2O has 4
SF6 has zero. All electrons are paired and all are shared. There no unshared electrons. Zero unshared electrons is the smallest number of unshared electrons of those listed. You reasoning is superb. You just answered the wrong question.
