Question

Which of the following represents saponification reaction?

Options

• `"CH"_3"COONa" + "NaOH"overset("CaO")(->) "CH"_4 + "Na"_2"CO"_3`

• `"CH"_3"COOH" + "C"_2"H"_5"OH" overset("H"_2"SO"_4)(->)"CH"_3"COOC"_2"H"_5 + "H"_2"O"`

• 2CH₃COOH + 2Na → 2CH₃ COONa + H₂

• CH₃COOC₂H₅ + NaOH → CH₃ COONa + C₂ H₅OH

Answer 1

CH₃COOC₂H₅ + NaOH → CH₃ COONa + C₂ H₅OH

Explanation - 

On treating with sodium hydroxide, which is an alkali, the ethyl acetate, which is an ester, is converted to alcohol and sodium acetate (salt of carboxylic acid). This reaction is known as saponification because it is used in the preparation of soap.
