Chemistry C7

Methane, Ethane, Propane and Butane.

They burn to produce water and carbon dioxide (they are only hydrocarbon chains so can't produce much else!)

They contain C-C and C-H bonds which are fairly unreactive, especially with aqeuos reagants.

Methanol, Ethanol, Propanol and Butanol.

They have the functional group 'OH'

Methanol is used as an industrial solvent, and also as a feedstock in the manufacture of organic chemicals.

Ethanol is used in perfurmes, aftershaves, and is mixed with petrol to be used as a fuel.

Their reaction with sodium is gentle, whereas water plus sodium is vigorous and sodium plus an alkane do not react.
