What type of smell is associated with esters?

  1. Earthy

  2. Floral and flowery

  3. Woody

  4. Spicy

The correct answer is: Floral and flowery

Esters are known for their characteristic sweet, fruity, and often floral scents, which are typical of many essential oils and aromatic compounds. This floral and flowery aroma comes from the presence of esters in various plants and fruits, contributing to their fragrant profiles. For example, esters like ethyl acetate and isoamyl acetate will evoke pleasant scents in fruits such as bananas and apples, as well as in a range of floral oils. This makes them significant in both aromatherapy and perfumery, where desired scents can enhance mood and evoke memories associated with floral and fruity aromas. The other scent profiles, such as earthy, woody, or spicy, do not accurately represent the typical characteristics associated with esters, further reinforcing why floral and flowery is the most appropriate description.
