Key Word Definitions
• Saturated hydrocarbon: Hydrocarbon which only have
______________________bonds.
• Combustion: A chemical reaction between a fuel and an oxidant (always oxygen),
accompanied by the production of heat and conversion of chemical species.
• Substitution reaction: An atom or a functional group in a particular chemical
compound is replaced by another atom or group.
Key Points
1. Hydrocarbons are mainly used as fuels. The burning of a substance in air is called
_________. The main products of this burning from hydrocarbons
are_____________, ___________and_________. The reaction is exothermic chemical
reaction(gives out heat energy).
2. ___________ combustion means burning in a lack of air (not enough_________).
During this kind of combustion methane gas burns with a ________ flame (unlike
the______and_____ flame seen in complete combustion).
3. Write balanced equations for the combustion reactions of C 5H12 with oxygen both
complete and incomplete .
4. Write two balanced equations for the reaction of bromine with propane in light to
form the compound C3H6Br2 .
