1.	Which of the following acids on Kolbe’s electrolysis gives ethane?(a) HCOOK(b) HCOONa(c) CH3COOK(d) CH3CH2COONaThe question was posed to me in an interview.My doubt stems from Carboxylic Acids Chemical Reactions in division Aldehydes, Ketones and Carboxylic Acids of Chemistry – Class 12
Answer» Right option is (c) CH3COOK The explanation: Aqueous solutions of sodium or POTASSIUM salts of carboxylic ACIDS on electrolysis, undergo decarboxylation and FORM hydrocarbons having twice the number of carbon atoms as present in the alkyl GROUP of the acid. Since ethane has two C atoms, the alkyl group of the acid should be CH3.
