Ask EduPadi AI for a detailed answer
Correct Option: C
When a carboxylic acid reacts with an amine, an amidation reaction occurs, forming a carboxamide and water. The reaction involves the replacement of the -OH group of the carboxylic acid with the amino group (-NH2) of the amine.
Note: Option "b" (Alcohol and carboxylic acid) represents an esterification reaction, not the formation of a carboxylic acid. Option "d" (Aldehyde and alcohol) represents an aldol condensation reaction, not the formation of a carboxylic acid.
