Which ester is represented by the chemical formula CH3COOCH3?

Explanation:
An ester has a carbonyl carbon (C=O) that is singly bonded to an oxygen which connects to another alkyl group. The formula CH3COOCH3 shows a methyl group (CH3) attached to the carbonyl carbon on one side and a methoxy group (OCH3) on the other side, giving the structure CH3-C(=O)-O-CH3. That arrangement corresponds to methyl acetate. The other formulas would place different groups around the carbonyl or use an incomplete/incorrect connectivity, so they do not represent this ester.
