Answer 1

Concepts and Reason

This problem is based on the concept of carboxylic acid and alkenes to Schiff’s base compound conversion.

Carboxylic acids are the compounds which contain carboxylic group $\left( { - {\rm{COOH}}} \right)$ in their chemical structures. Alkenes are hydrocarbons that contain double bond in their structure. They can be converted to Schiff’s base by following a series of chemical processes.

Fundamentals

Conversion of carboxylic acid involves the formation of alcohols which on further oxidation results in the formation of carbonyl compound which on treatment with amines results in formation of Schiff’s base whereas conversion of alkenes to Schiff’s base involves the hydroboration-oxidation to form alcohol which on further oxidation results in the formation of carbonyl compound which on treatment with amines gives Schiff’s base.
