Q:

Which type of molecule is CF4?

A) nonpolar, with a symmetrical distribution of charge	B) polar, with an asymmetrical distribution of charge
C) nonpolar, with an asymmetrical distribution of charge	D) polar, with a symmetrical distribution of charge

Answer & Explanation Answer: A) nonpolar, with a symmetrical distribution of charge

Explanation:

CF4 is tetrahedral.

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.

Hence, CF4 is nonpolar molecule with a symmetrical distribution of charge.
