The mechanism for formation of an amide is as follows taking example of propanoic acid and ethylamine:
The hydrolysis of amide so formed can give back the carboxylic acid and amine.
(b)
Interpretation:
The carboxylic acid and amine or ammonia needs to be identified from which each amide be synthesized.
Concept Introduction:
Amides are formed by a reaction with a carboxylic acid and an amine which are the functional groups. This results in the formation of amide bond, in which OH group of carboxylic acid reacts with one of the H in amine group and CO-NH bond is formed. This bond is known as an amide bond.
The mechanism for formation of an amide is as follows taking example of propanoic acid and ethylamine:
The hydrolysis of amide so formed can give back the carboxylic acid and amine.

Introduction to General, Organic and Biochemistry
- Give each of the following amines an IUPAC name. a. b. c.arrow_forwardThe amines are organic weak bases which are nitrogen-containing. In the early days of organic chemistry, basic amines derived from natural sources were known as “vegetable alkali”, but they are now referred to as alkaloids. The study of alkaloids provided much of the growth of organic chemistry, phytochemistry and natural products chemistry. It remains a fascinating area of research. Please search for one naturally occurring alkaloid and provide the following: Name of the alkaloid and show its structure. Identify using arrows the polar bonds in the structure Species from where it was isolated What was the use of this alkaloid in plants (if any)? What are the pharmacological, medicinal, or environmental uses or applications of this alkaloid (if any)?arrow_forwardAmines as Bases. Explain ?arrow_forward
