Question

why do esters with higher molecular weight not have strong fragrance?​

Answer 1

Answer:

Basically, fragrances reach other person through sense of smell. So, the strength of the fragrances depends a lot on its evaporation, which is strongly related to the boiling point. ... Esters with higher molecular weight do not have a strong fragrance because it has higher boiling point.
