Match the reactions given in Column I with the names given in Column II. Column I Column II A. CH 3 OH + CH 3 COOH → H + CH 3 COOCH 3 + H 2 O 1. Addition reaction B. CH 2 = CH 2 + H 2 → Ni CH 3 — CH 3 2. Substitution reaction C. CH 4 + Cl 2 → Sunlight CH 3 Cl + HCl 3. Neutralisation reaction D. CH 3 COOH + NaOH → CH 3 COONa + H 2 O 4. Esterification reaction

Esterification reaction: It is the reaction between carboxylic acid (RCOOH) with an alcohol (ROH) to form an ester (RCOOR) and water. CH 3 OH + CH 3 COOH → H + CH 3 COOCH 3 + H 2 O Addition reaction: In this one molecule combines with another molecule to form a larger molecule with no other products. This reaction is also called hydrogenation. CH 2 = CH 2 + H 2 → Ni CH 3 — CH 3 Substitution reaction: In this type one atom or a group of atoms takes the place of another atom. CH 4 + Cl 2 → Sunlight CH 3 Cl + HCl Neutralisation reaction: It is a chemical reaction in which acid reacts with a base forms salt and water. CH 3 COOH + NaOH → CH 3 COONa + H 2 O The matching of Column I and Column II is as given Column I Column II A. CH 3 OH + CH 3 COOH → H + CH 3 COOCH 3 + H 2 O Esterification reaction B. CH 2 = CH 2 + H 2 → Ni CH 3 — CH 3 Addition reaction C. CH 4 + Cl 2 → Sunlight CH 3 Cl + HCl Substitution reaction D. CH 3 COOH + NaOH → CH 3 COONa + H 2 O Neutralisation reaction
