Introduction
According to the definition by IUPAC, the former two are alkanes, whereas the third group is called cycloalkanes. Saturated hydrocarbons can also combine any of the linear, cyclic (e.g., polycyclic) and branching structures, and they are still alkanes (no general formula) as long as they are acyclic (i.e., having no loops).They also have single covalent bonds between their carbons.
Pre-Requisites:
Alkanes
Activity:
Kerosene.
Real Life Question:
What is classification of alkanes?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Alkanes | Hydrocarbons which contain only single bonds are called alkanes. They are called saturated hydrocarbons because there is hydrogen in every possible location. This gives them a general formula CnH2n+2. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Gasoline | A mixture of alkanes from pentane up to about decane. |
Real life uses :
Used mainly for heating and cooking purposes.
Places to visit :
Chemistry laboratory.
Practical examples around us
| Examples | Explainations |
|---|---|
| methyl | A methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms — CH3. |
What you learn in Theory:
Linear alkanes (general formula CnH2n + 2) wherein the carbon atoms are joined in a snake-like structure.
What you learn in Practice:
Branched alkanes (general formula CnH2n + 2, n > 3) wherein the carbon backbone splits off in one or more directions.
