What do you intend by a revision technique? to learn all kinds of chemical structures of alkanes? use the general formula to determine the structure of a certain alkane: C(n)H(2n+2) where n = 1, 2, 3.

'n' is the number of carbon atoms in an alkane. Methane for instance is has a carbon atom in the chemical structure, so n = 1. Then the chemical structure of Mehtane is CH4. Another example. Ethane has two carbon atoms in the chemical structure, so n = 2. C2H6 is the chemical structure.

I recommend you to learn how many carbon atoms exist in a certain alkane, so you are able to determine the chemical structure by the general formula. The names of some alkanes even reveal how many carbon atoms exist in the alkanes. Example: Pentan, derived from penta = 5, so five carbon atoms; Octane, derived from octa = 8, so eight carbon atoms.

I hope that my comment was helpful.
