CH2CCH3COOR

CH2CCH3COOR is a condensed structural formula that denotes an ester. In this representation, a carbonyl group is bonded to an alkoxy group OR' and to an alkyl or substituted alkyl fragment CH2CCH3. However, as written it does not uniquely specify connectivity or stereochemistry; several constitutional isomers could match the formula depending on how the CH2CCH3 fragment is attached to the carbonyl carbon. Consequently, CH2CCH3COOR is not a single, unambiguous compound without additional structural information.

Esters have the general formula R-CO-OR' and are common functional groups in organic chemistry. They are typically

Synthesis and transformations of esters are central to organic synthesis. Typical routes include acid-catalyzed esterification, base-

Safety and handling depend on the specific ester. Esters are often flammable liquids with varying volatility
