Question

What is the general formula of amide?

Answer 1

A nitrogen atom is connected to a carbonyl carbon atom in the amide functional group. The molecule is a simple amide if the two remaining bonds on the nitrogen atom are connected to hydrogen atoms. A substituted amide is formed when one or both of the remaining bonds on the atom are linked to alkyl or aryl groups.

Complete answer:
Amide is a nitrogen-containing chemical that belongs to one of two classes: ammonia and amines. Covalent amides are compounds that are neutral or very weakly acidic when the hydroxyl group (OH) of an acid is replaced by an amino group.
An amide, also known as an organic amide or a carboxamide in organic chemistry, is a molecule having the generic formula RC(=O)NR′R′′, where R, R', and R′′ are organic groups or hydrogen atoms, respectively.
CO-NH is the typical chemical formula for amide groups.
Amides can be found in both nature and technology. Proteins and key plastics like Nylons, Aramid, and Kevlar are polymers with amide groups (polyamides) connecting their units; these connections are easy to produce, provide structural rigidity, and resist hydrolysis. Numerous other significant biological molecules, as well as many medications such as paracetamol, penicillin, and LSD, are amides.
Except for formamide, which is a liquid, covalent amides formed from ammonia are solids; those with fewer than five carbon atoms are water soluble. They are both organic and inorganic solvents as well as non-conductors of electricity. Even low-molecular-weight covalent amides have high boiling points.

Note:
Derivatives of carboxylic acids are the names given to simple amides. The suffix -amide replaces the -ic ending of the common name or the -oic ending of the International Union of Pure and Applied Chemistry (IUPAC) nomenclature of the carboxylic acid.
