Q. 14.41 - An Introduction to General, Organic, and Biological Chemistry

Question

Write the IUPAC and common names, if any, for each of the following amides:

a.

b.

c.

Step-by-Step Solution

Answer

(part a) This structure has two carbon atoms; its IUPAC name is ethanamide, and its common name is acetamide.

(part b) This structure has four carbon atoms; its IUPAC name is butanamide, and its common name is butyramide.

(part c) This structure's IUPAC name is $N-$ethyImethanamide, and its common name is $N-$ethyl formamide.

Step1: Introduction. (part a)

Amides are carboxylic acid derivatives in which the hydroxyl group has been replaced by an amine. When carboxylic acid reacts with a substrate, a reaction called Amidation occurs

This response removes a water molecule as well as the carboxylic acid, but it also combines amine molecules.

Step2: Given Information (part a).

Find out what the IUPAC and common names.

Step3: Explanation (part a).

This structure has two carbon atoms; its IUPAC name is ethanamide, and its common name is acetamide.

Step4: Given Information (part b).

Find out what the IUPAC and common names.

Step5: Explanation (part b).

This structure has four carbon atoms; its IUPAC name is butanamide, and its common name is butyramide.

Step6: Given Information (part c).

Find out what the IUPAC and common names.

Step7: Explanation (part c).

Because the ethyl bond is formed to the nitrogen atom in this structure, the prefix $N-$ comes before the name amides. This structure's IUPAC name is $N-$ethyImethanamide, and its common name is $N-$ethyl formamide.
