Amides are organic compounds that feature the functional group -CONH2 attached to a nitrogen atom, and are widely found in the pharmaceutical and polymer industries. The IUPAC (International Union of Pure and Applied Chemistry) nomenclature for amides follows a specific pattern, differing from the nomenclature of amines and carboxylic acids, compounds with which amides share structural characteristics. Considering a common example of an amide, acetamide (CH3CONH2), identify the main criterion used in the IUPAC nomenclature of amides and explain how it applies to the naming of this compound.

The main criterion for naming amides is to identify the main chain containing the -CONH2 functional group and name it with a suffix indicating the presence of the functional group (-amide), without omitting the location of the functional group on the chain if there is more than one. In the case of acetamide, the main chain is ethane and the suffix is -amide, resulting in the name ethanamide.

The main criterion for naming amides is to identify the main chain containing the -NH2 functional group and name it with a suffix indicating the presence of the functional group (-amine), as in the case of acetamide which would be ethylamine.

To name amides, it is necessary to identify the main chain containing the -COOH functional group and name it with a suffix indicating the presence of the functional group (-acid), as in the case of acetic acid which would be propanoic.

In the process of naming amides, the -CONH2 functional group is considered a substituent and is named before the main chain, followed by the chain name and the -amide suffix, as in the case of N-ethylpropanamide.

The nomenclature of amides follows the criterion of identifying the main chain with the highest number of carbons and adding the suffix -amide, regardless of the position of the functional group on the chain, as in the case of N,N-dimethylethanamide.
