Can ethanoic acid will show isomerisation with ester ? If yes give det...
☛ The reaction between Acid and Alcohol to produce ester as the product is called Esterification Reaction.
☛ Esters is a Sweet smelling substance. It is used in perfumes, manufacturing of dye and flavouring agent.
▪▪▪▪ PREPARATION ▪▪▪▪
☛ They are formed when ethanol reacts with ethanoic acid in the presence of acid, as a catalysts(H2SO4).
☛ This reaction resulting in the formation of Esters is known as " Esterification ".
☛ The chemical equation for the reaction involved -
CH3COOH + CH3CH2OH ➡ CH3COOC2H5 + H2O. ( Include H2SO4 as a catalyst. )
•• CH3COOH = Ethanoic acid.
•• CH3CH2OH = Ethanol.
•• CH3COOC2H5 = Ethyl Acetate.
☛ When esters(CH3COOC2H5) with sodium hydroxide(NaOH) forms sodium ethanoate ( CH3COONa) as the main product and ethanol (C2H5OH).
▪ CH3COOC2H5 + NaOH ➡ CH3COONa + C2H5OH + heat.
▪▪ This reaction is known as Saponification Reaction, Alkaline Hydrolysis or Esters Hydrolysis.
▪▪ This reaction is used in the production of soap and hence the name is Saponification Reaction.
▪▪ It is an exothermic reaction since heat is evolved.
