more examples
-
Starting from the alkane with 5 carbons the names start with the math agrupation of the number, for example 5=pent
-
-
cracking
Process where large molecules are broken down into smaller, more useful molecules
With large, alkane chains they can be broken down into a smaller chain and an alkene

Catalyst
Catalyst such as Zeolites are used for alkanes can be heated to higher temperatures with less energy

Formation of crude oil
- Sea creatures living millions of years ago
- Die and fall to the sea bed
-
Acid rain and pollution
Sulfur dioxide
Hydrocarbons contain impurities, one of those impurities is sulphur
When the hydrocarbon is combusted, the sulphur combines with oxygen (oxidises) and forms sulfur dioxide
-
-
Nitrogen oxide
-
This can be reduced by
catalytic convreters
A catalytic converter causes a reaction between CO and nitrogen oxides to produce carbon dioxide and water

Effects of CO2
Greenhouse effect
The greenhouse effect is a natural process where certain gases stop heat from getting out of earth atmosphere
-
The greenhouse effect can be harmful if too much greenhouse gasses are in the atmosphere, increasing the total temperature
Organic families
-
-
Organic compounds contain carbon covalently bonded to hydrogen, and often other elements
Isomers
-
Types of isomers
Positional
Compounds with the same molecular formula but different structures due to different positions of the same functional group on the same carbon skeleton
-
Functional
Compounds with the same molecular formula but with atom arrangements to give dfferent functional groups
-
An example of this would be an isomer inwhich one of them is an alcohol and the other one is an alkane
