12. Carboxylic acids
i. Carboxylic acids :
Organic compounds containing carboxyl groups
Called carboxylic acids. The carboxyl group is made up
Carbonyl, >C = O and hydroxyl, -OH group, hence, its name is
carboxyl group
18. I. by oxidation of primary alcohols :
General methods of preparation
R - CH2OH +2[O] R-COOH + H2O
CH3CH2OH + 2[O]
kmnO4/H+
CH3COOH + H2O
II. by oxidation of aldehydes :
Ethyl alcohol
Acetic acid
R - CHO + [O] R-COOH
CH3CHO + [O] CH3COOH
Acetaldehyde Acetic acid

Which of the following compounds would undergo aldol condensation, which
the Cannizzaro reaction and which neither? Write the structures of the
expected products of aldol condensation and Cannizzaro reaction.
31. Write structural formulas and names if four possible aldol condensation
products from propanal and butanal. In each case, indicate which aldehyde
acts as nucleophile and which as electrophile
32. An organic compound with molecular formula C9H10O forms 2,4- DNP
Derivative, reduces tollen’s reagent and undergoes cannizzaro reaction. On
vigorous oxidation, it gives 1,2- benzenedicarboxylic acid, identify compound.
