PIT_PIT [208]

Proteins, nucleic acids, and carbohydrates are grouped by common structural features found within their group. lipids can be grouped based on their high solubility in nonpolar solvents, and their preponderance of nonpolar groups.

Non-polar solvents cannot dissolve a polar compounds since no opposite charge exist, and the polar compound is not attracted. It is this becuase of absence of partial charge that also makes these molecules non-polar. Some of examples of non-polar solvents include benzene, hexane, pentane, toluene, etc.

Higher the solubility of a compound is that the larger the amount of the compound which can dissolve in a solution.
