Final answer:
The empirical formula of a compound related to sorrel is Rutin, and the molecular formula is Sorbic acid, which is used as a preservative to control the growth of molds in acidic foods like sorrel.
Step-by-step explanation:
The question refers to the Empirical Formula (EF) and Molecular Formula (MF) of compounds present in sorrel. When we talk about the compounds related to sorrel in the context of food chemistry and preservatives, options A, B, C, and D present different chemical compounds.
Option D mentions Rutin as the EF compound and Sorbic acid as the MF compound. Rutin is a flavonoid found in certain fruits and vegetables, including sorrel, which is known for its antioxidant properties. Sorbic acid is a chemical preservative that is effective at controlling microbial growth, including molds, especially in acidic foods. Because the question is about compounds related to sorrel, the combination of Rutin as a naturally occurring compound in sorrel and Sorbic acid as a food preservative closely associated with sorrel preservation makes option D the correct answer.
