Mini-Quiz: Polar and Non-Polar Molecules

by Ron Kurtus (revised 16 September 2015)

Take this Mini-Quiz to check your understanding of the lesson material.



1. Why is H2O a polar molecule?

It will freeze at polar temperatures

Since Hydrogen is polar and so is Oxygen, then the combination is also polar

The molecule has positive (+) charges on one side and negative (-) charges on the other

2. Why isn't a molecule like CO2 a polar molecule?

Its configuration is symmetrical with negative (-) charges on both ends

CO2 is a polar molecule

It only consists of three atoms

3. What happens if you mix two liquids, where each consists of polar molecules, and the liquids don't react chemically?

The combination turns to a solid substance

The combination becomes a solution

Such liquids will not mix

If you got all three correct, you are on your way to becoming a Champion in Chemistry. If you had problems, you had better look over the material again.
