Alkanes and Alkenes
- Alkanes
- Saturated hydrocarbons
- Have single bonds only
- Means they are
saturated with
hydrogen
- Means they are
saturated with
hydrogen
- Saturated hydrocarbons
- Alkenes
- Unsaturated hydrocarbons
- Have at least one double bond
- Unsaturated hydrocarbons
- Addition reactions
- Carbon-Carbon double
bond in alkenes means
another atoms can be
added
- Hydrogen and Bromine
can be added in this way
- Hydrogen and Bromine
can be added in this way
- When hydrogen is added to an alkene
(hydrogenation), the corresponding
alkane is formed.
- When Bromine is added to an
alkene it forms a dibromoalkane.
- Double bond breaks
and 2 bromine atoms
attach
- Its useful as it can be used to test for presence of an alkene
- Brown/orange bromine water will react
with alkenes and its colour disapears as
the product formed is colourless
- Brown/orange bromine water will react
with alkenes and its colour disapears as
the product formed is colourless
- Double bond breaks
and 2 bromine atoms
attach
- Carbon-Carbon double
