Alkanes


Alkane
In organic chemistry, an alkane, or paraffin means little affinity) para mean little affin mean affinity  is an acyclic saturated hydrocarbon. an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single.
Formula
Alkanes have the general chemical form is CnH2n+2.
In an alkane, each carbon atom is sp3-hybridized with 4 sigma bonds (either C–C or C–H), and each hydrogen atom is joined to one of the carbon atoms (in a C–H bond) CH4 .

Q: How I make methane from alkane ?
Ans:
General formula of alkane is CnH2n+2.
Put the value of carbon, in methane Carbon is 1
So n = 1
CH4 Methane
 
C1H2(1)+2  = CH4
