What to Focus On
- Hydrocarbons contain only carbon and hydrogen.
- Alkanes are saturated hydrocarbons.
- Alkenes contain C=C double bonds.
- Methane is also called marsh gas and fire damp.
- Natural gas contains about 85 per cent methane.
- Methane has tetrahedral geometry with bond angle 109°28′.
- Methane combustion is highly exothermic.
- Main chlorination product of methane in excess methane is methyl chloride.
- Methane iodination is slow and reversible.
Common Mistakes to Avoid
Ethylene is not the first member of the alkene series because methylene should come first.
When methane reacts with chlorine in excess chlorine, carbon tetrachloride is the main product.
Iodination of methane and ethane behave the same way.
Memory Tips
Alkanes are saturated hydrocarbons with formula CnH2n+2
Methane is also called marsh gas and fire damp
Methane prepares from sodium ethanoate and soda lime
Methane combustion is highly exothermic
