Question

What are esters ?how they are prepared? list two uses of esters.

Answer 1

HI !

Esters are sweet smelling substances.

They are formed when ethanol reacts with ethanoic acid , in the presence of acid as catalyst (H₂SO₄).

This reaction resulting in the formation of ester is known as "esterification"

Ethanoic acid -> CH₃COOH

Ethanol -> CH₃CH₂OH

Ethyl Acetate(Ester) -> CH₃COOC₂H₅

                                                   Conc. H₂SO₄

CH₃COOH +  CH₃CH₂OH  ----------------------------> CH₃COOC₂H₅ + H₂O

Uses :-

<> Used in perfumes

<> Used in manufacture of dye

<> Used as a flavouring agent
