write about a esterification and saponification

$\Large\fbox{\color{purple}{ SOLUTION }}$

★ ESTERIFICATION ★

• when carboxylic acid reacts with alcohol in presence of concentrated sulphuric acid to form Easter this reaction is called esterification

★ FORMULA ★

$\small\mathcal\blue{CH_{3}COOH + C_{2}H_{5}OH \longrightarrow\: CH_{3}COOC_{2}H_{5} +H_{2} O}$

★ SAPONIFICATION ★

• when easter is heated with sodium hydroxide solution it gets hydrolysed to form the corresponding alcohol and sodium salt of the carboxylic acid .this alkaline hydrolysis of esters is known as saponification as it is used in the preparation of soap

★ FORMULA ★

$\small\mathcal\blue{CH_{3}COOC_{2}H_{5}+ NaOH \longrightarrow\: CH_{3}COONa + C_{2}H_{5}OH}$
