    \u00a0Preparation of Methane (CH4<\/sub>).
    \n<\/strong>Methane is prepared in the laboratory by heating ethanoate salt with corresponding alkalis e.g Sodium ethanoate and soda-lime.<\/p>\n

    \u00a0Physical Properties
    \n<\/strong>1. Methane is a colourless and odourless gas
    \n2. It is slightly soluble in water.

    \u00a0Chemical Properties.
    \n<\/strong>\"\"\/1.\u00a0\u00a0\u00a0\u00a0Combustion:- Methane burns in air or oxygen to produce steam, carbon(iv) oxide and a lot of heat CH4<\/sub> + 2O2<\/sub> 2H2<\/sub>O + CO2<\/sub>.
    \nThe general equation of alkanes for combustion is represented as

    \n– Isomers are compounds having the same molecular formula but different structural formula.
    \n– As the number of carbon atoms in a molecule increases, the number of isomers also increases, for example, pentane has the following three isomers.
