Lecithin  >  Triglyceride  >  Palmitic acid  >  Glycerol

Vedclass · Answer

(D) To determine the correct order, we compare the molecular weights of the given molecules:$1$. Glycerol $(C_3H_8O_3)$: Molecular weight $\approx 92 \, g/mol$.$2$. Palmitic acid $(C_{16}H_{32}O_2)$: Molecular weight $\approx 256 \, g/mol$.$3$. Triglyceride: Formed by one glycerol and three fatty acids (e.g., palmitic acid), molecular weight $\approx 800+ \, g/mol$.$4$. Lecithin (Phospholipid): Contains a glycerol backbone, two fatty acids, a phosphate group, and choline, making it larger than a simple triglyceride, molecular weight $\approx 800-900+ \, g/mol$.Thus, the order of increasing molecular weight is: Glycerol    Triglyceride  >  Palmitic acid  >  Glycerol.

Column $I$	Column $II$
$(a)$ Oleic acid	$(p)$ Short-chain saturated fatty acid
$(b)$ Palmitic acid	$(q)$ Long-chain saturated fatty acid
$(c)$ Crotonic acid	$(r)$ Short-chain unsaturated acid
$(d)$ Butyric acid	$(s)$ Long-chain unsaturated fatty acid

Select the correct option based on molecular weight.
