Cho các este:C6H5OCOCH3 (1); CH3COOCH=CH2 (2);  CH2=CH-COOCH3 (3); CH3-CH=CH-OCOCH3 (4)

* Hướng dẫn giải

\(1. CH_{3}COOC_{6}H_{5}+H_{2}O \rightarrow CH_{3}COOH+C_{6}H_{5}OH\)

\(2. CH_{3}COOCH=CH_{2}+H_{2}O \rightarrow CH_{3}COOH+CH_{3}CHO\)

\(3. CH_{2}=CH-COOCH_{3}+H_{2}O \rightleftharpoons CH_{2}=CH-COOH+CH_{3}OH\)\(4. CH_{3}-CH=CH-OCOCH_{3} \\ CH_{3}COO-CH=CH-CH_{3}+H_{2}O\rightarrow CH_{3}COOH+CH_{3}-CH_{2}-CHO\)
