Verified step by step guidance

Understand that the energy stored in molecules is often related to the number of carbon atoms and the type of bonds present. Generally, molecules with more carbon atoms and more C-H bonds store more energy.

Identify the molecular structure of each compound: Sucrose (C12H22O11), Arachidic acid (C20H40O2), Glucose (C6H12O6), and Behenic acid (C22H44O2).

Consider the number of carbon atoms in each molecule: Glucose has 6, Sucrose has 12, Arachidic acid has 20, and Behenic acid has 22.

Evaluate the types of bonds: Carbohydrates like glucose and sucrose have more oxygen atoms, which typically store less energy compared to fatty acids like arachidic and behenic acids, which have long hydrocarbon chains.

Rank the molecules based on the number of carbon atoms and the type of bonds, considering that fatty acids generally store more energy per mol than carbohydrates due to their long hydrocarbon chains.
