CHEM - Cracking and test for unsaturated hydrocarbons

Cracking Hydrocarbons 

Short chain hydrocarbons 

• highly flammable 
• low boiling point 
• low viscosity 
• very useful 

Long chain hydrocarbons 

• less flammable 
• more viscous 
• higher boiling point 
• not as useful 

To make them more useful we need to split them up…
