Name the different types of hydrocarbon reactions.
: the burning of hydrocarbons in the presence of oxygen. Alkanes, Alkenes, Alkynes all undergo combustion. The hydrocarbon reacts with oxygen to form carbon dioxide
: Only alkanes do this. One or more hydrogen atoms on an alkane are replaced by one or more other types of atoms, the most common being a halogen
) + Cl2
) ----> CH3
) + HCl(g
The general form for halogen substitution reactions is:
- R--H + X2 --> R--X + HX
- Alkane Halogen Alkil halide Hydrogen halide
: Alkenes and alkynes do these, in which atoms add across the multiple bond.
For example, ethene reacts with chlorine gas to form dichloroethane.
They can also react with Hydrogen in hydrogenation reactions
. In the presence of the appropriate catalyst, propene reacts with hydrogen gas to form propane:
convert unsaturated hydrocarbons into saturated hydrocarbons, such as partially hydrogenated vegetable oil
