On whether ethyl acetate is a ketone
in the world, there must be its own rules. According to chemical reasons, the genus of ethyl acetate and ketone is analyzed.

Ketone, the molecule contains carbonyl (\ (C = O\)), and the carbonyl group is connected to hydrocarbon at both ends. The structure of ethyl acetate is\ (C_ {4} H_ {8} O_ {2}\), and the structural formula is\ (CH_ {3} COOCH_ {2} CH_ {3}\). Although it contains carbonyl, the carbonyl group is connected to methyl at one end and\ (- OCH_ {2} CH_ {3}\) at the other end. It is not a hydrocarbon group, but a genus of ester groups.

Esters and ketones are of different types. Esters are formed by the esterification reaction of acids and alcohols, and have specific functional groups and chemical properties. Ketones have unique chemical properties and reactivity, and the two cannot be confused.

In summary, ethyl acetate is a non-ketone substance, and the carbonyl group in its structure does not match the definition of ketone. Knowing this, the true meaning of the chemical substance category can be obtained, which cannot be ignored in scientific research.
