Question

Give a balanced equation for ethanol reacting with ethanoic acid in presence of h2 s o4

Answer 1

REACTION WITH ACETIC ACID:

When alcohols react with acetic acid in the presence of conc. H2SO4 at high temperature ,the respective esters are produced and the process is known as esterification.

CH3OH + CH3COOH -----conc.H2SO4--->-CH3COOH+H2O

C2H5OH + CH3COOH ----conc.H2SO4-->

CH3COOC2H5 +H2O

Answer 2

${\bold{\green{\huge{Your\:Answer}}}}$

✍️ Ethanoic acid is warmed with ethanol in the presenceof a few drops of concentrated sulphuric acid a sweet smelling Ester called ethyl ethanoate is formed.

✍️ This reaction to form an ester is called esterification.

✍️ This reaction is also used as a test for ethanoic acid.

✍️ The reaction is slow and reversible.

✍️ To reduce the chances of the reverse reactionhappening, the ester is distilled off as soon as it is formed.

✍️ Reaction :-

♦ $CH_3COOH$ + $C_2H_5OH$ ---> $CH_3-COO-C_2H_5$ + $H_2O$

♦ Ethanoic acid + ethanol ---> ethyl ethanoate + water
