1.	Which of the following observations is correct andis used in the identification of carboxylic acids
Answer» Carboxylic acids liberates `CO_(2)` gas from `NaHCO_(3)` SOLUTION They produce FRUITY SMELL of esters when heated with alcohol in presence of conc. `H_(2)SO_(4)`. Both (a) and (b) Iodoform test Solution :`RCOOH + NaHCO_(3) rarr RCOONa + H_(2)CO_(3) rarr CO_(2)` (`RCOOD` more acidic than `H_(2)CO_(3)`) Hence carboxlyic ACID liberates `CO_(2)` from solidum bicarbonate solution. `RCOOH + R'OH overset("conc." H_(2)SO_(4))rarr underset((" Fruity smell"))underset(" Easter")(R-COOR' + H_(2)O)` Hence they give fruity smell when warmedwith alcohol in the presence of conc. `H_(2)SO_(4)` Hence choice (c ) is CORRECT as (a) and (b) both are correct. Any carboxylic acid even `CH_(3)COOH` does not give iodoform test as the H-atom attached to C is not more acidic than H-atom attached to O. Hence (d) is incorrect.
