Fuels From Crude Oil

Question 1

What is Crude Oil?

Answer 1

Crude Oil is a compound straight from the ground. It is made up of different compounds called hydrocarbons

These can be separated by fractional distillation to create different types of fuels for example Petrol or Diesel

Question 2

What is fractional distillation?

Answer 2

The process of seperating the different hydrocarbons from crude oil.

This is done by heating crude oil up a tower.

Each hydrocarbon’s chain is of different lengths (and different boiling points) and condenses at different heights because of thjd

Question 3

As the carbon chain increases what becomes higher and what decreases?

Answer 3

As the carbon chain length increases, the boiling point becomes higher. Viscosity also increases

However flammability decreases

Question 4

What are Hydrocarbons made of?

Answer 4

Hydrocarbons are made of Carbon and Hydrogen only

Question 5

What is the general formula for an Alkane?

Answer 5

The general formula for an Alkane is:

Cn H2n + 2

Meaning whatever C is, H is it doubled plus 2

Question 6

What is the general formula for an Alkene?

Answer 6

The general formula for an Alkene is:

Cn H2n

Meaning whatever C is, H is it but doubled

Question 7

What do we use to Remember Meth- Eth- Prop- But- ?

Answer 7

(1) Monkeys = Meth-
(2) Eat = Eth-
(3) Peanut = Prop-
(4) Butter = But-
