Interpretation: Amongst the given compounds, the lipid is to be identified.
Answer to Problem 1SAQ
Solution:
(b)
Explanation of Solution
The lipids are a diverse group of naturally occurring organic compounds and chemical components of the cell. They are characterized by their solubility in nonpolar organic solvents (e.g., ether, chloroform, acetone, and benzene) and general insolubility in water. The long alkyl chain present in the fatty acid makes it nonpolar and insoluble in water. Therefore, it is a lipid.
The multiple hydroxyl groups present in the molecule in option (a) make it polar and soluble in water. Hence, option (a) is not correct. It is a carbohydrate. The
Thus, the correct option is (b).
