Answer
This statement is incorrect. Triglycerides can undergo oxidative rancidity, especially if they contain unsaturated fatty acids. Unsaturated fats are more prone to oxidation due to the presence of double bonds.
Step 2
B. The triglyceride will hydrolyze to carbon dioxide and water.

Answer
This statement is incorrect. Triglycerides hydrolyze to glycerol and fatty acids, not directly to carbon dioxide and water. Hydrolysis involves the addition of water, resulting in the breakdown of the molecule.
Step 3
C. The triglyceride has three carbon-carbon double bonds.
