Introduction
Properties depend only on the functional group
Pre-Requisites:
Hydrocarbons, functional groups
Activity:
Observe properties of two homologous compounds.
Real Life Question:
Can varying only the carbon chain length of a compound, change its properties?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Homologous series | These are the compounds where functional groups are same, only the length of chain varies. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Stick models | Make hydrocarbons, and then replace hydrogen atoms by different elements. Now increase the size of carbon chains. |
Real life uses :
This knowledge helps us predict properties of group of compounds.
