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:
Isomerization
Activity:
Crude oil.
Real Life Question:
What is Isomerization?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Isomerization | Processes in which straight-chain alkanes are heated in the presence of a platinum catalyst. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| liquefied petroleum gas | A flammable mixture of hydrocarbon gases used as a fuel in heating appliances and vehicles. |
Real life uses :
They are the main components of natural gas; they are normally stored as gases under pressure.

Chemistry laboratory.
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:
In isomerization, the alkanes become branched-chain isomers. In other words, it does not lose any carbons or hydrogens, keeping the same molecular weight.
What you learn in Practice:
Butane is the most common alkane that is put under the process of isomerization, as it makes many branched alkanes with high octane numbers.
