What type of solvents have a sweet, strong, fruity odor that is pleasant to smell?

Ester solvents are characterized by their sweet, strong, and fruity odors, making them quite pleasant to smell. This characteristic is due to the chemical structure of esters, which are derived from the reaction between alcohols and acids. They are commonly found in various paints, coatings, and other products because their pleasant scent can improve the overall sensory experience during application.

In contrast, alcohols typically have a less pleasant odor, often described as sharp or medicinal. Ketones, while they may have a somewhat sweet smell, do not generally possess the fruity characteristics associated with esters. Aromatic solvents are known for their strong and intense odors, which can be more pungent and less pleasant compared to the fruity essence of esters. Thus, ester solvents stand out for their unique and appealing fragrance, making them the correct choice in this context.
