Which type of molecule is CF4? (1) polar, with a symmetrical distribution of charge

(2) polar, with an asymmetrical distribution of charge

(3) nonpolar, with a symmetrical distribution of charge

(4) nonpolar, with an asymmetrical distribution of charge

The answer is (3). CF4 is tetrahedral, so you can consider it to be kind of spherically balanced. Since the four F atoms have the same electronegativity values, there is no bias in electron distribution toward any one. Therefore, electron/charge distribution is symmetrical, which also means that the molecule is nonpolar.
