Question

Differentiate between polar and non polar substances with examples of each.

Answer 1

If a molecule is polar, it said to have a positive and negative electrical charge.A non-polar molecule, on the other hand, does not have enough charge unlike polar molecules. Non-polar molecules are distributed in a symmetrical manner and do not contain abundant electrical charges that are attached on them. An example of a substance with a polar molecule is water. Water is composed of polar molecules because of the arrangement of the atoms, plus there is an abundant number of positive and negative electrical charges. Other examples under the gas category are: ammonia, sulfur, particularly sulfur dioxide, and lastly hydrogen sulfide.
Non-polar substance examples are hydrocarbons such as gasoline and toluene. In gases, most gases are non-polar such as methane, carbon dioxide, neon, krypton, and xenon.
In mixing substances, you cannot mix a polar and non-polar substance. For example, water is polar while oil is non-polar. When you try to mix them, it will not combine. However, when you mix alcohol, which is a polar substance, and water, it will mix because both are polar substances.

Summary:

1.Polar substances have enough positive and negative electrical charges on the atoms while non-polar substances do not have abundant charges.
2.Polar substances will mix with polar substances but polar substances will not mix with non-polar substances.
3.An example of polar substances are water and alcohol. An example of non-polar is oil.
