What type of reaction do alkenes typically undergo?
Alkenes = Addition reactions.
Fill in the blank: The process of breaking down larger hydrocarbons into smaller ones is called __________.
Cracking
What is the main use of hydrocarbons in everyday life?
Fuels for energy.
True or False: Hydrocarbons can be found in natural gas.
True
What is the simplest alkene?
Ethene (C2H4).
What is the boiling point trend for alkanes as the carbon chain length increases?
The boiling point increases as the carbon chain length increases.
What is the structural feature of benzene?
Benzene has a hexagonal ring structure with alternating double bonds.
What is the main environmental concern associated with burning hydrocarbons?
They release greenhouse gases
True or False: All hydrocarbons are flammable.
True

Fill in the blank: The process of adding hydrogen to unsaturated hydrocarbons is called __________.
hydrogenation
What is a saturated hydrocarbon?
Contains only SINGLE carbon bonds
What is the main component of natural gas?
Methane (CH4).
What is an unsaturated hydrocarbon?
Contains at least 1 carbon DOUBLE bond
What happens when you react bromine with an alkene?
Double bond breaks and reacts with bromine
Solution LOSES its orange colour
What happens when you react bromine with an alkane?
There is NO double bond for bromine to react with so…
Solution KEEPS its orange colour
What is the general formula for alkenes?
CnH2n
