➜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?

Answer:
Methane is CH4, it is a colourless, odourless flammable gas which is main constituent of nature gas. Electron dot structure Bond formed in this compound is single covalent bond. (i) These compounds are poor conductors of electricity because they form covalent compounds that does not consist of free electron or free ions. (ii) Have low melting and boiling point because of weak Vanderwaal's force of attraction. CH4 + 2O2 → CO2 + 2H2O Combustion reaction takes place producing carbon dioxide and water.
Answer⤵
A covalent bond is formed when an element shares its valence electron with another element. ... Thus as methane is formed of carbon and hydrogen, the type of bond is covalent bond. Covalent compounds are poor conductors of electricity because they do not not contain free electrons or free ions.
