Which organic compound is responsible for the characteristic aroma of fruits?

Explanation

Esters give fruits their sweet smell. They form when alcohols react with acids. Different esters create different fruit aromas.

Alkanes have no smell. Alkynes smell unpleasant. Amines smell like fish or ammonia.

Remember: Banana smell is pentyl ethanoate. Pineapple smell is ethyl butanoate. Both are esters.
