Alkane is
also known as organic compounds or paraffin. One alkane compound contain one
hydrogen and carbon atoms that are arranged in tree like structure . In alkane,
all carbon atoms are single bonded. The general formula of alkane is CnH2n+2.
Each carbon atom has our bonds and every hydrogen atom is bonded with carbon
atom. Waxes are higher alkanes, in which carbon atoms are greater than 18. Alkanes
are less reactive as compared to other alkenes and alkynes. Alkanes are mostly
present in mostly natural gas and petroleum. Alkanes are saturated hydrocarbons which
contain only single bond and also known as structural because it contains only
maximum numbers of hydrogen atoms. Alkanes compounds show three dimensional
shape and covalent bond is present between alkanes compounds. In methane C-H
bonds are directed to make tetrahedral structure at the angle of 109 degree.
Alaknes does not show reaction with air but in heated form they show slow response
in this regard. Alkanes are used as fuel
because, the reactions of alkanes are exothermic. The chemical properties of alkanes compounds
are similar but physical properties are various such as density or boiling
point of compounds. Alkanes are also known as homologous. Alkanes molecules easily make ring or chain
like structure. Alkane can react only in
the form of gas for example methane react in the form of natural gas or
petroleum.
Characteristics of Alkane
General Formul is CnH2n+2.
1. Alkanes are present in Natural gas ant Petroleum.
2. Alkanes are Less Reactive
3. Alkanes have Low Melting Point
4. Alkanes are Soft
5. Alkanes are Crystalline in solids.
6. Alkane contain non polar molecules.
7. Alkanes are also less
reactive to many laboratory reagents.
8. If the numbers of molecule increases then the melting and
boiling points of alkane also increases.
9. Melting point increase due to strong intermolecular forces.If
the weight of molecule is higher than the more 10. electrons are present.
