You identify alkanes by their lack of reactivity.

I presume that you are trying to distinguish alkanes from alkenes.

The general tests for alkenes are:

  • They decolourize bromine water
  • They decolourize aqueous potassium permanganate

If your compound does not decolourize bromine water or aqueous potassium permanganate, it is an alkane.
