- Alkanes, also known
as paraffins, are chemical compounds that consist only of the elements
carbon (C) and hydrogen (H)(i.e.,hydrocarbons), wherein these atoms are
linked together exclusively by single bonds without any cyclic
structure.
- Alkanes belong to a
homologous series of organic compounds in which the members differ by a
constant relative atomic mass of 14.
- An alkyl group is a
functional group or side-chain that, like an alkane, consists solely of
singly-bonded carbon and hydrogen atoms, for example a methyl or ethyl
group.
- Saturated
hydrocarbons can be linear (general formula CnH2n+2) wherein the carbon
atoms are joined in a snake-like structure, branched wherein the carbon
backbone splits off in one or more directions, or cyclic wherein the
carbon backbone is linked so as to form a loop.
- According to the
definition by IUPAC, the former two are alkanes, whereas the third group
is called cycloalkanes.
- The simplest
possible alkane is methane, CH4. There is no limit to the number of
carbon atoms that can be linked together, the only limitation being that
the molecule is acyclic, is saturated, and is a hydrocarbon.
- Alkanes are not very
reactive and have little biological activity. Alkanes can be viewed as a
molecular scaffold upon which can be hung the interesting
biologically-active/reactive portions of the molecule.
- Alkenes or alkynes
react with hydrogen in the presence of nickel catalyst at 200-300°C to
form alkanes. Other catalysts that can be used are platinum and
palladium.
- Alkyl halides
undergo reduction with nascent hydrogen to form alkanes.
- When the sodium salt
of a carboxylic acid is heati strongly with sodalime , a molecule of
carbon dioxide is split off as carbonate Amdahl alkane is formed. Notice
that the alkane so produced contains one carbon less than the original
acid.
- Alkyl magnesium
halides are obtained by treating alkyl halides with magnesium in
anhydrous ether. These on treatment with water give alkanes.
- Alkanes from
hexadecane upwards form the most important components of fuel oil and
lubricating oil.
- Many solid alkanes
find use as paraffin wax, for example, in candles. This should not be
confused however with true wax, which consists primarily of
esters.
- Propane, for
example, is used in the propane gas burner, butane in disposable
cigarette lighters. The two alkanes are used as propellants in aerosol
sprays.
- The first four
alkanes are used mainly for heating and cooking purposes, and in some
countries for electricity generation.
- Methane and ethane
are the main components of natural gas; they are normally stored as
gases under pressure.
- Related to
environmental or aquatic toxicology, alkanes are generally not of much
toxicological concern .
