Q. 14.71 - An Introduction to General, Organic, and Biological Chemistry

Question

Write the IUPAC name for each of the following:

a.

b.

c.

Step-by-Step Solution

Answer

(Part a) $N-$ethyl ethanamide is the IUPAC name for this structure.

(Part b) Propanamide is the IUPAC name for this structure. 

(Part c) The compound's IUPAC name is $3-$methyl butanamide.

Step1: Introduction (Part a)

Amides are carboxylic acid variants in which the hydroxyl group has been replaced with an amine. Amidation is a reaction that occurs when carboxylic acid reacts with a substrate. A water molecule is removed in this reaction, and also the carboxylic acid and amine molecules combine to form the amide.

Step2: Given Information (part a).

To Enter the IUPAC name here.

Step3: Explanation (part a).

Because the ethyl complex is formed to the nitrogen atom in this structure, the prefix $N-$ comes before the name amide. $N-$ethyl ethanamide is the IUPAC name for this structure.

Step4: Given Information (part b).

To Enter the IUPAC name here.

Step5: Explanation (part b).

This structure has three carbon atoms. Propanamide is the IUPAC name for this structure.

Step6: Given Information (part c).

To Enter the IUPAC name here.

Step7: Explanation (part c).

This structure has four carbon atoms, with a methyl group attached to the third carbon atom. The compound's IUPAC name is $3-$methyl butanamide.
