Aldehydes: Aldehydes are the organic compounds in which carbonyl group is attached to one hydrogen atom and one alkyl or aryl group. Using chromium oxide : Toluene or substituted toluene is converted to benzaldehyde in presence of chromic oxide in acetic anhydride. Ketones react with ethylene glycol under similar conditions to form cyclic products known as ethylene glycol ketals.
In case of unsymmetrical ketones cleavage occurs in such a way that keto group stays with smaller alkyl group. The methyl group is converted to haloform.
On basic hydrolysis carboxylate ions are formed which on further acidification forms corresponding carboxylic acids. Anhydrides on hydrolysis forms corresponding acid s.
Carboxylic acids are more acidic than phenols. The strength of acid depends on extent of ionization which in turn depends on stability of anion formed. Carboxyl group in benzoic acid is electron withdrawing group and is meta directing. The revision notes covers all important formulas and concepts given in the chapter.

CBSE Class 12th Chemistry Notes: Aldehydes, Ketones and Carboxylic Acids (Part - I)
The classes of organic compounds containing carbonyl group CO as the functional group are aldehydes, ketones, carboxylic acids and their derivates. These are collectively called carbonyl compounds. Nature of carbonyl group: Oxygen atom in carbonyl group is far more electronegative than carbon atom. Hence carbonyl carbon acquires positive charge and carbonyl oxygen carries negative charge.
The carbonyl compounds in which carbonyl group is bonded to oxygen are known as carboxylic acids. By Login, you agree to our Terms and Privacy Policies.
