why do esters smell

Do all esters smell fruity?
The simple esters tend to have pleasant odors.
In many cases, although not exclusively so, the characteristic flavors and fragrances of flowers and fruits are due to compounds with the ester functional group.
An exception is the case of essential oils.
Why do acids smell bad?
The strong smell of acetic acid is due to the presence of a chemical called acetate, which is highly volatile and can easily be detected by the human nose.
Why is ester sweet smelling?
- The intermolecular force of attraction between the esters is weak. - Due to this less intermolecular force of attraction the ester compounds are volatile in nature. - There is no existence of the hydrogen bond also in esters. - This volatile nature of esters makes us smell._{15 mar. 2021}
Esters have a very weak intermolecular force of attraction between the molecules.
Due to this weak attraction, the other gases can easily mix with the fragrance of the ester.
And due to which there is a difference in the fragrance of the lab ester smell and the fragrance found in nature.

Esters have a distinct odor due to the weak intermolecular interactions they exhibit. In the gas phase, this encourages ester molecules to penetrate and hit the nose. Esters are not soluble in water hence it floats on water causing it to easily get mixed in the gas phase. Hence, they smell stronger in water.
