What do some properties of hydrocarbons depend on |
The size of their molecules (Larger or smaller) |
|
|
State the 3 properties of hydrocarbons and describe what is meant by each |
- Viscosity: Thickness/stickiness of a fluid - Boiling point: Temperature at which a liquid turns to gas - Flammability: How easy a hydrocarbon burns |
|
|
Give an example of a long chain hydrocarbon and what happens to it in terms of its properties |
Butane: - Viscosity increases as size of hydrocarbon increases - Flammability decreases as size of hydrocarbon increases - Boiling point increases as size of hydrocarbon increases |
|
|
In terms of Viscosity if the molecule are a small chain hydrocarbon what does mean (2 things) |
- Viscosity is low meaning the stickiness between molecules is low - They hydrocarbons flow very quickly as they are not very viscous |
|
|
What are is the state of the 4 alkanes at room temperature and explain why |
They are gases: Because their boiling points are lower than room temperature |
