Question

What is
Saponifacation and esterification

Answer 1

 ${\mathfrak{\red{\huge{Hiii}}}}$

In esterification, carboxylic acid and alcohols react in presence of concentrated sulphuric acid to form fruity sweet smelling compounds called esters. Concentrated H 2 SO 4 acts as a catalyst and a dehydrating agent.

Saponification is the reverse reaction
Ester reacts with strong base or an acid to give back the alcohol and carboxylic acid. It is called saponification because it is used in the manufacture of soaps.

Answer 2

✔️✔️Esterification is when an acid and an alcohol react to give an ester and water. 

⭕️Esterification reaction is defined as the reaction between alcohol and acetic acid to form a sweet smelling substance used in "flavor" called Ester.

➖CH3CH2OH + CH3COOH ---› CH3COOCH2CH3* + H2O

*CH3COOCH2CH3 is ethoxy ethane

⭕️Esterification is the chemical reaction in which we obtain ethyl ethanoate and water by reacting ehanol and ethanoic acid.

✔️✔️Saponification is the reverse of this. That is, the hydrolysis of ester to give acid and alcohol. 

⭕️Saponification reaction is defined as the constituents used in making the "ester" can be regained in their original form.

⭕️It is used in the preparation of soaps.

⭕️Saponification is the reverse of esterification.

⭕️ In this reaction sodium hyroxide is reacted with ethyl ethanoate to obtain soap and ethanol.

➖️CH3COOCH2CH3 + H2O ----› CH3CH2OH + CH3COOH

✔️✔️Kindly note the differences too!

✔️✔️✔️Difference :-

⭕➖️Saponification means process of preparation of soap.
➖Esterification means process of preparation esters.


⭕️➖Saponification involves reaction between carboxylic acid and a base.
➖Esterification involves reaction between alcohol and carboxylic acid.

⭕➖️Esterification needs  as a catalyst ➖Saponification do not need.
