Question

(a) What happens when ethanol reacts with ethanoic acid in the presence of a little of concentrated sulphuric acid? Write equation of the reaction involved.
(b) What happens when ethanol is heated with concentrated sulphuric acid at 170°C? Write the equation of the reaction which takes place.

Answer 1

Answer:

1.C2H5OH + CH3COOH ⇨ CH3COOC2H5 + H2O

2.C2H5OH=C2H4 + H2O at 170°C

Explanation:

1.ethyl ethanoate is formed

2.at 170°C it produces ethylene gas

Answer 2

Ethyl Ethanoate is Formed when Acetic Acid reacts with Ethanol

Explanation:

A.)When Ethanol reacts ethanoic acid in the presence of a few drops of concentrated sulphuric acid, a sweet-smelling ester names ethyl ethanoate is formed.  

The chemical equation for the above reaction is :

$CH_3COOH + C_2H_5OH$ --------------> $CH_3COOC_2H_5 + H_2O\ in\ presence\ of\ conc.H_2SO_4$

B.) Ethene ($CH_2=CH_2$) is formed when ethanol is heated with cone. $H_2SO_4$ at 170° C. This reaction is known as dehydration.

$CH_3CH_2OH$ -------------->$CH_2=CH_2 + H_2O$

                     $conc. H_2SO_4$
