What is methane? Draw its electron dot structure. Name the type of bonds formed in this compound. Why are such compounds:(i) poor conductors of electricity? and(ii) have low melting and boiling points?What happens when this compound bums in oxygen?
Methane is a Hydrocarbon formed by the combination of carbon with Hydrogen.
Its molecular formula is CH4. It is the main greenhouse gas. The type of bond formed in methane is a covalent bond.
Electron dot structure of methane (CH4):
(i) Compounds containing covalent bonds are poor conductors of electricity because no free electrons or free ions are present in them to conduct electricity.
(ii) Compounds containing covalent bonds have low melting and boiling points because of weak Vander Waal’s force of attraction between them so less energy is required to break the force of binding them.
When methane burns in oxygen, the following reaction occurs:
$CH_4 + 2O_2 → CO_2 + 2H_2O + heat + light$
Carbon dioxide and water are produced.
