Write the molecular formula of the following carbon compounds :(i) Methane(ii) Propane(b) Carbon compounds have low melting and boiling points. Why ?

(i) The molecular formula for Methane is CH4. This means it consists of one carbon atom and four hydrogen atoms.

(ii) The molecular formula for Propane is C3H8. This means it consists of three carbon atoms and eight hydrogen atoms.

(b) Carbon compounds, specifically organic compounds, have low melting and boiling points because they are held together by covalent bonds. Covalent bonds are not as strong as ionic bonds, so they require less energy to break. This is why organic compounds, which are primarily made up of carbon, have lower melting and boiling points compared to inorganic compounds.
