Which of the following represents saponification reaction?
पर्याय
`"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

उत्तर
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.
