
Structure: CONH2
A carboxylic acid contains the -COOH group, and in
an amide the -OH part of that group is replaced by an
-NH2 group.




Amides result from carboxylic acids.
Amides are the most common non-basic functional
group.
The melting points of amides are high for the size of
the molecules because they can form hydrogen bonds.
Amides have different chemical properties from
amines, and are really weak bases.

Amides are named by adding the suffix ”amide” after
the acid dropping the “ic, oic, or acid.”

methanamide

acetamide

Amides (R-CO-NH2) take the suffix –amide if the
carbon in the amide group cannot be included in the
main chain .

Acid formation of an ester from an amide to alcohol.

Esters reacting with amines (ammonia) to form an amide.

Heating Carboxylic Acids and amines together to form an
amide

Methanamide- HCONH2

Enthanamide- CH3CONH2

Propanamide- CH3CH2CONH2

Formamide-CH3NO

Butanamide- C4H9NO


Amides are used in industries such as paper
making, crayons, ink, and the rubber
industries.
Amides have an unsubstituted aliphatic
carboxylic acid in them that makes them
suitable for making plastic because of its
powerful solvent properties.


Nylon is made up of long-chain-fiber-forming
polyamides with reoccurring amide groups.
The first polyamide was Nylon 66, produced
by the reaction of adipic acid (a 6-carbon
dibasic acid) and hexamethylene diamine (a 6carbon aliphatic diamine)
Nylon was produced as an alternative to silk,
and is used in things such as winter jackets,
yarn, and zip ties.
