Textbook problem 2E.25

Postby Ariana 1D » Sat Dec 09, 2023 4:11 pm

Can someone explain how CCl4 is a polar molecule yet, SF4 is a non polar molecule? I thought it would be the other way around since CCl4 is symmetrical and SF4 has lone pair electrons but the textbook answers says otherwise.

That is a mistake from the book. CCl4 is non polar since it has a tetrahedral arrangement that is symmetrical thus bond dipoles cancel out and SF4 is a polar molecule, having a see saw shape that is asymmetrical so bond dipoles do not cancel out.
