esters: Organic compounds formedby reaction between alcohols andacids (see illustration). Esters formedfrom carboxylic acids have the generalformula RCOOR′. Examples areethyl ethanoate,CH3COOC2H5, andmethyl propanoate, C2H5COOCH3. Esterscontaining simple hydrocarbongroups are volatile fragrant substancesused as flavourings in thefood industry. Triesters, moleculescontaining three ester groups, occurin nature as oils and fats.

Esters are a class of organic compounds formed by an acid reacting with alcohol. Methyl acetate (CH3COOCH3) is an example of an ester formed by acetic acid reacting with methyl alcohol. Esters containing simple hydrocarbons are volatile and fragrant substances that are used as flavorings in the food industry. Triesters occur in nature as oils and fats, which are esters of glycerol and long chain fatty acids.
