Question

What are the uses of amide?

Answer 1

Amide is an organic compound which contains the group $-CON{{H}_{2}}$. They have many numbers of chemical and commercial uses.

Complete answer:
- We know that an amide group contains the group $-CON{{H}_{2}}$. Amides have a wide range of uses varying from solvents to drugs.
- Acetamide $\left( C{{H}_{3}}CON{{H}_{2}} \right)$ and dimethylformamide $\left( HCON{{\left( C{{H}_{3}} \right)}_{2}} \right)$ are the two amides which are used as sulfa drugs, solvents and nylons.
- The chemical formula of urea is $N{{H}_{2}}CON{{H}_{2}}$ and it is an amide. It is a crystalline compound which we obtain as the end product metabolism of protein and in the end, it is excreted with the urine in mammals.
- We synthesize urea from ammonia and carbon dioxide in large quantities in order to use it in the fertilizers and animal feed.
- Urea is also used in the manufacturing process of a class of polymers which are also known as urea-formaldehyde resins and it is mainly used in the process of making plastics.

Additional information:
- Amides can be of three types: Primary amides $\left( RCON{{H}_{2}} \right)$ having one carbon atom attached to the nitrogen, secondary amides $\left( RCONHR \right)$ having two carbon atoms attached to the nitrogen and tertiary amides $\left( RCON{{R}_{2}} \right)$ having three carbon atoms attached to the nitrogen.
- Amides are formed when carboxylic acids react with an amine. The reaction is given below-
$RCOOH+{{R}^{'}}N{{H}_{2}}\to RCO{{O}^{-}}NH_{3}^{+}{{R}^{'}}\xrightarrow{\Delta }RCONH{{R}^{'}}+{{H}_{2}}O$

Note:
Don’t confuse the group amine with amide. They may sound similar, but they are quite different. Amines are those which have the group $-N{{H}_{2}}$ attached to it. On the other hand, amides are those which have $-CON{{H}_{2}}$ attached to it. Amides have an extra carbonyl group $\left( C=O \right)$ present in it.
