Question

which of these compounds might be an ingredient in commercial sunscreen? check all that apply.

Explanation:

Sunscreen ingredients often include compounds that can absorb UV light. Compounds with aromatic (benzene - like) rings and hydroxyl (-OH) or other functional groups that can interact with UV radiation are common. The first compound has a phenolic (-OH on benzene) and ester group, and the second has a phenolic and carbonyl - aromatic structure, both of which are typical of UV - absorbing sunscreen ingredients (like derivatives of cinnamic acid or benzophenone - type compounds). The third compound has cyclohexane rings and an alkyne, which is less typical for UV absorption in sunscreen. So the first and second compounds are likely sunscreen ingredients.

Answer:

The first compound (with the phenolic ring, ester, and alkyl chain) and the second compound (with two aromatic rings, a phenolic - OH, and a methoxy group) are the ones that might be in commercial sunscreen. So check the boxes for the first and second compounds.
