Introduction
Alkanes consist only of hydrogen and carbon atoms, all bonds are single bonds, and the carbon atoms are not joined in cyclic structures but instead form an open chain. They have the general chemical formula CnH2n+2.
Pre-Requisites:

crude oil

Practical examples around us
| Examples | Explainations |
|---|---|
| Butane | Butane is an organic compound with the formula C4H10 that is an alkane with four carbon atoms. Butane is a gas at room temperature and atmospheric pressure. |
What you learn in Theory:
The mechanism of aromatization of the alkane is the relative rates of aromatization of various alkanes with different numbers of carbon atoms and the relative yields of the isomeric aromatics.
What you learn in Practice:
Aromatization of alkanes having one to four carbon atoms per molecule to aromatics, such as benzene, toluene and xylenes (BTX), uses a catalyst of a crystalline zeolite on which platinum has been deposited, specifically a platinum-containing ZSM-5.
