reaction of alkenes

Reactions of alkenes
With oxygen – combustion
Less energy and Smokey flame due to incomplete
C3H6+ 4 ½ O2 -> 3h20 + 3co2
Functional Group – are groups of one or more atoms or bonds (except double bond) of
distinctive chemical properties.
Homologous Series - family of hydrocarbons with similar chemical properties who share the
same general formula.
A displayed formula - shows all the bonds in the molecule as individual lines.
2A. General formula of Alkenes:
Cn H2n
2B. Octane has 8 carbons, how many carbons does it have:
C8 H19
3. Why are alkenes unsaturated?
Because they have a double carbon bond.
