Quick Answer. A polar compound is a molecule with a geometric arrangement of one side carrying a positive charge and the other side a negative charge. Water, ammonia, sulfur dioxide and hydrogen sulfide are examples of polar compounds. Continue Reading.
When comparing a polar and non-polar molecule with similar molar masses, the polar molecule generally has a higher boiling point, because of the dipole-dipole interaction between their molecules. The most common form of such an interaction is the hydrogen bond, which is also known as the H-bond. non-polar compound occurs when there is an equal sharing of electrons between two different atoms. Examples of household non-polar compounds include fats, oil and petrol/gasoline. Therefore (per the oil and water rule of thumb), most non-polar molecules are water insoluble (hydrophobic) at room temperature.
