Detailed explanation-1: -Answer and Explanation: The characteristic that all lipids have in common is that they are nonpolar molecules, which means they do not dissolve in water.
Detailed explanation-2: -Lipids. Fats, oils, and waxes are all examples of lipids. There are lots of lipids, but they all share the trait of being at least partially hydrophobic (meaning they won’t mix with water).
Detailed explanation-3: -Lipids are chemical substances that are nonpolar in nature. Because water is a polar molecule, they are only soluble in nonpolar solvents and insoluble in water.
Detailed explanation-4: -Lipids are a diverse group of compounds that are united by a common feature. Lipids are hydrophobic (“water-fearing”), or insoluble in water. Lipids perform many different functions in a cell. Cells store energy for long-term use in the form of lipids called fats.
Detailed explanation-5: -Lipids are all insoluble in polar solvents like water but highly soluble in the non-polar or weakly polar organic solvents, including ether, chloroform, benzene, and acetone.
