Question

poor conductor of electricity have low melting and boiling point then what happen when its component burnt with oxygen​

Answer 1

Answer:

Methane is a colorless, odourless and highly flammable gas which is the main component of natural gas.

Electron dot structure of methane is- (Image attached)

The covalent bonds are present in between four hydrogen atoms and the single carbon atom at the centre of the molecule.

(i) Methane is a poor conductor of electricity because in methane all bonds are covalent bonds and therefore no free electrons are present in the molecule that can help in conducting electricity.

(ii) Covalent compounds have low intermolecular forces of attraction between the molecules and thus show low melting and boiling points. Since methane is also a covalent compound thus methane has very low melting and low boiling point.

When methane is burned in the presence of oxygen, it forms C{O}_{2}CO

with water as the product of the reaction.

C{H}_{4} + {O}_{2} \longrightarrow C{O}_{2} + {H}_{2}OCH
