1.	a) Whatis an esterification reaction ? (b) Write a chemical equation in each case to represent the following types of chemical reaction of organic compounds : (i) Oxidation reaction (ii) Addition reaction (iii) Substitution reaction.
Answer» Solution :When carbonic acid reacts with alcohol n the presenee of cone. `H_(2)SO_(4),` pleasant fruity smelling COMPOUND is formed this type of reaction is called esterification reaction. `underset("Ethanoic acid")(CH_(3)COOH_(1))+ underset("Ethanol")(C_(2)H_(5)OH_(1))underset(H_(2)SO_(4))overset("ALKALINE")rarr underset("Ethyl ethanoate")(CH_(3)COOC_(2)H_(5(1)))+ underset("Water")(H_(2)O_(1)`) (i) Oxidation reaction : `underset("Ethanol")(CH_(3)CH_(2)OH)+2[O] underset("KMnO"_(4))overset("Alkaline")rarr underset("Ethonoic")(CH_(3)COOH+H_(2))O` (ii) Addition rection: `underset ("Ethene")(CH_(2))=CH_(2)+H_(2)underset("573K")overset("Ni")rarr CH_(3)- CH_(3)` (iii) Substitution reaction : `underset("METHANE")(CH_4)+Cl_(2) overset("Sunlight")rarr underset("Methylchoride")(CH_(3)Cl+HCl)`
