Lipids are composed mostly of hydrocarbons which is nonpolar.
|
|
|
Lipids have hydrogen bonds that repel the hydrogen bonds in water.
|
|
|
Lipids have more neutrons on their atoms making the compound neutral.

Detailed explanation-1: -Answer and Explanation: Lipids are classified as nonpolar substances and will not mix with water (c is correct). Lipids are hydrophobic, which causes them to ‘fear’ water and favor interactions with other nonpolar compounds.
Detailed explanation-2: -Most lipids are non-polar (having no charged areas) or only slightly polar, with a very few charged areas. Water mixes with hydrophilic (water-loving) compounds by sticking to their charged groups. Since lipids lack charged groups, the water molecules have nothing to stick to and don’t mix with them.
Detailed explanation-3: -This is because they are primarily nonpolar carbon-carbon or carbon-hydrogen bonds in hydrocarbons. Hydrophobic, or “water repelling, ‘’ non-polar compounds cannot dissolve in water. In a cell, lipids serve numerous purposes.
