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 burns in oxygen?
Methane is a carbon compound which is widely used as a fuel and is a major component of Compressed Natural Gas (CNG) and biogas.Its formula .
The type of bonds formed in methane is covalent bond.
(i) The bond is formed by sharing of electrons so no charged particles are formed. As no charged particles are present to conduct electric current, they are poor conductors of electricity.
(ii) Covalently bonded molecules have weak intermolecular force of attraction. So, they have low melting and boiling points.
When methane burns in oxygen, carbon dioxide and water are produced along with the release of large amount of heat and light.
