Detailed explanation-1: -Explanation of the correct option: 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-2: -Lipids are fatty, waxy, or oily compounds that are soluble in organic solvents and insoluble in polar solvents such as water.
Detailed explanation-3: -The lipids found in the membrane consist of two parts: hydrophilic (water soluble) and hydrophobic (water insoluble). The hydrophobic portion of the lipids is the non-polar long hydrocarbon chains of two fatty acids.
Detailed explanation-4: -Lipids are a large and diverse class of biological molecules marked by their being hydrophobic, or unable to dissolve in water. The hydrophobic nature of lipids stems from the many nonpolar covalent bonds. Water, on the other hand, has polar covalent bonds and mixes well only with other polar or charged compounds.
