Verified step by step guidance1
To solve this problem, we need to understand the key characteristics of each reaction type: hydrogenation, acid-catalyzed hydrolysis, saponification, and oxidation.
Hydrogenation (A) involves the addition of hydrogen (H2) to unsaturated compounds, typically converting carbon-carbon double bonds (C=C) to single bonds (C–C). This matches statement III.
Acid-Catalyzed Hydrolysis (B) is a reaction where water, in the presence of an acid, breaks down compounds. This process does not directly match any of the given statements.
Saponification (C) is the process of breaking down fats or oils with a base to form glycerol and salts of fatty acids. This matches statements I and IV.
Oxidation (D) involves the increase in the oxidation state of a molecule, often forming carbon-oxygen double bonds (C=O). This matches statement II.
