Anonymous users2024-02-11From the chemical formula of A, it can be seen that there is only one double bond or one ring in A, and from A+H2O (acid hydrolysis) B+C, A may be an ester, then B and C are acids and alcohols. By the relative molecular mass of B and C is equal.
B and C are known as CH3COOH and CH3CH2CH2OH or (CH3)2CHOH. Bubbles are slowly produced by B+NA and C+NaOH salt + H2O B is an alcohol and C is an acid, so the structure of B is CH3CH2CH2OH or (CH3)2CHOH, and the structure of C is CH3COOH.
The equation for the reaction of c and ethanol is:
CH3COOH+HOCH2CH3=CH3COOCH2CH3+H20 (catalyzed by acid or base).
