R-NH₂ :The amine functional
group contains a basic
nitrogen atom with a lone pair
Amines of electrons. As such, the
group is derivative of
ammonia, in which one or
more hydrogen atoms have
been replaced by a carbon-
containing substituent. The
suffix "-amine" is used when
naming an amine compound.
Amides are molecules that contain nitrogen
atoms connected to the
Amides carbon atom of a carbonyl
group.
A chemical combination of
two organic molecules that
Condensation reaction
releases water.
Example: Alcohol + Carboxylic
Acid→ Ester + Water
Soaps are sodium or potassium
carboxylic acids salts, produced
from the hydrolysis of
Soap fats in a chemical reaction
called saponification. Each
soap molecule has a long
hydrocarbon chain, sometimes
called its 'tail' (hydrophobic),
with a hydrophilic carboxylate
'head'.
