Amines
are organic derivative of ammonia (NH3 ) in which one or more alkyl or aryl groups have replaced ammonia hydrogen atoms
-NH2
functional group of amines
less than 109 degrees
The bond angles of amine can be measured less than the regular angle of a tetrahedron which is
due to the distortion caused by the presence of lone pair
why is the bond angle of amine less than the regular angle of a tetrahedron
due to the large dipole moment of the lone pair electron
why are amiens polar?
Primary amine
nitrogen atom is bonded to one hydrocarbon group and two hydrogen atom.
Secondary amine
- nitrogen atom is bonded to two hydrocarbon groups and one hydrogen atom.
Tertiary amine
nitrogen atom is bonded to three hydrocarbon groups and no hydrogen atoms.
Quartenary ammonium salts
nitrogen atom is bonded to four hydrocarbon
the negative charge will become a formal positive charge
in quarternary ammonium salts what happens to the nitrogen
Primary and Secondary amines
can exhibit hydrogen bonding
Tertiary amines
cannot perform hydrogen bodning
O-H bodns or N-H bonds
tertiary accept H-bonds from what molecules

• Simple alkyl group. Add the suffix –
-alkanamine
alkyl group is complex, the compound is named as an
Aryl amines
are named as a derivative of aniline
Primary amines
which as a higher boiling point?
Tertiary amine
which has a lower boiling point
less than 5
amine carbons requires how many number to become water soluble
greater than 5
amine carbon numbers that becomes sparingly soluble
low molecular weights such as trimethylamine
Amines that has fishlike odor
Cadaverine, Putrescine
the breakdown of enzyme of the fish protein froms what
Amines
s are considered the most abundant and is the richest in chemistry.
Bioregulation
responsible in the regulation of some bioactivity in both plants and animals.
acetylcholine, dopamine, serotonin
Amines that are - neurotransmitters in the body are mostly amines such as
Neurotransmitter
They assist in passing nerve impulses from one cell to another throughout the body.
Thiols
mercaptans, are analogue of alcohols
-SH
functional group of thiols
Methanethiol
is a toxic, extremely flammable, colorless gas with a smell like rotten cabbage.
Methanethiol
It is one of the main chemicals that cause bad breath and the odor of flatulence.
Mercapto
is added when -SH group is a substituent.
Monoterpenoid thiol
responsible for the mesmerizing scent of a grapefruit
furan-2- ylmethanethiol
the aroma of roasted coffee
S-H bonds
which is weaker S-H or O-H bonds
Ethyl mercaptan
are added to natural gas to serve as an easily detectable warning in case of leaks.
Dimercarprol
2, is used as an antidote for mercury, arsenic and lead poisoning
