How can we recognize polar and no polar molecules?

polar molecules have an unequal distribution of charges whilst non polar molecules are equally shared between atoms or elements producing no charged end.

Organic-

There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids); each is an important cell component and performs a wide array of functions.

Inorganic-

Water. perhaps most important and most abundant. molecule in the body; electrolytes (ions) molecules that tend to disperse in solution into charged atoms; gasses; carbohydrates.

Hope it helped! :)
