Answer :

Methane is a gas which is colourless and and odorless. It is a hydrocarbon with formula CH₄. Where as Hexane is an alkane containing 6 carbon atoms. Its molecular formula is C₆H₁₄. For the structure refer the figure given below.

Coming to the properties there are both physical and chemical properties.

Hexane is a colourless volatile liquid and undergoes combustion reaction, being a higher hydrocarbon it undergo thermal cracking.

It is commonly used as solvents, biodiesel production etc. Boiling point is 69⁰C and melting point is 95⁰C.

Methane is a gas which is colourless and odorless.  It  is lighter in air, slightly soluble in water, it is flammable.  boiling point is -162⁰C and melting point is -183⁰C.It is used as fuel, it is used in explosives.
