They are organic compounds
which are considered derivatives
of water wherein the hydrogens
are replaced by organic radicals.
Physical Properties
Solubility is similar to that of the
same molecular mass alcohols.
They are pleasant
smelling substances. Its
boiling point is similar to,
and are weakly polar
alkanes.
Nomenclature
It ends with the word ether at
the end of the common
classification as a halogen.
Functional Isomerism
Are functional isomers of
alcohols, they have the
same molecular formula
but different structural.
Alcohols
Physical Properties
Alcohols with low molecular
weight water soluble.
The density and the boiling point
increase with molecular weight.
Isomerism
Uses
Chemical Properties
Esterification reaction: They react
with carboxylic acids in medium hot
produciedo acid esters.
Oxidation reaction: The oxidation
involves oxygen that provides a
strong oxidizing agent.
Methods of Obtaining
Natural sources.
Alcoholic
fermentation: to
leave in the
absence of air like
corn or rye
produce
intoxicating
properties. Alcohol
has been obtained
by the
fermentation of
fruit, grains, etc..
Functional Group
They are organic compounds in which one or
more hydrogens from a hydrocarbon has been
replaced by one or more hydroxyl.
Nomenclature
Its completion in
systematic
nomenclature is
"ol" for the
common name
but the "ico" used.
Classification
Alcohols identification
They can be identified by its reaction with
sodium metal, the reaction product was as
follows hisdrógeno. To differentiate the
alcohols have the reaction test called Lucas.
Carboxylic Acid
Functional Group
They are caracterized by
their structure in the
carboxyl functional group
Nomenclature
Must end in "oic" in their
common name and its
completion is "ico".
Chemical Properties
The hydrogen of the carboxyl-OH
acid group gives character to these
compounds.
Physical Properties
Are liquid to nine carbons,
taking more are solid, unless
they contain double bonds.
Natural Sources and Uses
Halogenated
Nomenclature
Halogenated derivatives are named the
same way as the alkanes, considering the
halogen as a substituent in the main chain.
Functional Group
They are organic compounds in which one
or more hydrogens from a hydrocarbon have
been replaced by one or more halogens
Physical Properties
Solubility: soluble in water and
insoluble in nonpolar solvents
Boiling Point: Increases
with molecular mass
Density: Iodides and Bromides
are denser water
Chemical Properties
Formation of alcohols is a reaction in which
an alkyl halide reacts with a strong base.
Uses
Ketones and Aldehydes
Systematic Nomenclature
To name aldehydes termination
is "al" and ketones is "ona".
Common Nomenclature
Aldehydes name is related
to carboxylic acids. Ketones
Acetone called.
Chemical Properties
Oxidation reaction: Aldehydes are
easily oxidized and hydrogen is due to
carbon but ketones resist oxidation.
Functional Group
Consists of a carbon bonded
to oxygen with a double bond
and is called carbonyl.
Uses
Physical Properties
The polarity is larger with double bonds that simple. Its boiling
point is higher than that of the hydrocarbons. Its density is
lower than that of water. They are soluble in water.
Amines
Functional Group
Are nitrogen compounds can be
described as inorganic comuesto
ammonia derivatives.
Nomenclature
Form alphabetical naming alkyl or
aryl groups bonded to the amine
nitrogen and adding the suffix.
Amines and Cancer
If someone is exposed to the action of
two aromatic amines that are classified
as carcinogenic can get cancer.
Classification
Physical Properties
Have melting and boiling points that
increase with increasing molecular
mass. They are soluble in water.
