Lipids show solubility in which of the following solvents?
Correct answer: A. Ether
- A. Ether
- B. Water
- C. Alcohol
- D. All solvents
Explanation
Lipids are primarily nonpolar molecules, which makes them soluble in nonpolar solvents, such as ether. This is due to the 'like dissolves like' principle, where non-polar substances dissolve in non-polar solvents. Option A is correct because ether is a non-polar organic solvent. Option B is incorrect because water is a polar solvent and cannot dissolve non-polar lipids. Option C is also incorrect because it is also polar in nature. Option D is incorrect because lipids are not soluble in all solvents; they do not dissolve in polar solvents like water.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
