Structure and Classification of Aldehydes, Ketones, and Carboxylic Acids

In Class 12 Chemistry, understanding the structure and classification of aldehydes, ketones, and carboxylic acids is crucial. Aldehydes and ketones both contain the carbonyl group (C=O), but in aldehydes, it is bonded to at least one hydrogen, while in ketones, it is bonded to two alkyl or aryl groups. Carboxylic acids contain the carboxyl group (-COOH), combining a carbonyl and a hydroxyl group.

Physical and Chemical Properties of Aldehydes

Aldehydes are typically more reactive than ketones due to the presence of the hydrogen atom. They are polar compounds and have higher boiling points than hydrocarbons but lower than alcohols of comparable molecular weight. Aldehydes readily undergo oxidation to form carboxylic acids and participate in various addition reactions.

Physical and Chemical Properties of Ketones

Ketones, like aldehydes, are polar and can form hydrogen bonds with water, making smaller ketones soluble in water. They have higher boiling points than alkanes and ethers but lower than alcohols. Ketones are less reactive towards oxidation than aldehydes and are known for their nucleophilic addition reactions.

Physical and Chemical Properties of Carboxylic Acids

Carboxylic acids are known for their acidic nature due to the presence of the carboxyl group. They can form hydrogen bonds, making them generally more soluble in water. They have higher boiling points because of dimer formation through hydrogen bonding.

Preparation of Aldehydes and Ketones

Aldehydes can be prepared by the oxidation of primary alcohols, while ketones are obtained from the oxidation of secondary alcohols. Both can also be prepared through hydration of alkynes and the ozonolysis of alkenes.

Preparation of Carboxylic Acids

Carboxylic acids are commonly prepared by the oxidation of aldehydes and primary alcohols. Other methods include the hydrolysis of nitriles and esters and the Grignard reagent reaction with carbon dioxide.

Reactions of Aldehydes and Ketones

Aldehydes and ketones undergo a variety of reactions, including nucleophilic addition reactions, oxidation (aldehydes can be easily oxidized to carboxylic acids), reduction, and condensation reactions like aldol condensation.

Reactions of Carboxylic Acids

Carboxylic acids react to form esters (esterification), amides, anhydrides, and can undergo reduction to alcohols. They also participate in the Hell-Volhard-Zelinsky reaction and decarboxylation reactions.
