An ester is an organic compound where the hydrogen in the compound's carboxyl group is replaced with a hydrocarbon group. Esters are derived from carboxylic acids and (usually) an alcohol. While carboxylic acid has the -COOH group, the hydrogen is replaced by a hydrocarbon in an ester. It's a type of sweet smelling substance.

Examples of Esters

Ethyl acetate (ethyl ethanoate) is an ester. The hydrogen on the carboxyl group of acetic acid is replaced with an ethyl group.

Other examples of esters include ethyl propanoate, propyl methanoate, propyl ethanoate, and methyl butanoate. Glycerides are fatty acid esters of glycerol.
