And how would you draw P205?

Read the question very carefully. Did it ask if the molecule CCl4 is polar? (no)

This is not an MCAT question. This forum is not the appropriate place for homework questions.

It is asking for which contain polar covalent bonds, not which molecules are polar. A C-Cl bond is a polar covalent bond, even though CCl4 is tetrahedral and non-polar overall.

Oh, I see the distinction now. So a molecule could have polar bonds but be totally nonpolar?

Yes. If those polar covalent bones are symmetrical, the molecule can overall be nonpolar

Ah, I think I misinterpreted the question as well by equating molecule with polar bonds with molecule is polar, which is not always 100% true as in the case with CCl4.

Thank you @pseud0 and @Go_Pokes_11
