What reagent can be used to distinguish methane from propene. Give the equations of the ongoing reactions and name the resulting products in detail according to the systematic nomenclature. Describe the course of the experiment and the observed phenomena.

Methane (ch4) is a saturated hydrocarbon.

Propene (c3h6; ch2 = ch – ch3) is an unsaturated hydrocarbon, since it contains double bonds.
When an alkene interacts with an aqueous solution of potassium permanganate at room temperature, the solution becomes discolored:
In this case, the reaction between methane and potassium permanganate will not occur.
3ch2 = ch2 + 2kMno4 + 4h2o => 3ohch2
ch2oh + 2Mno2 + 2koh
ethanediol-1,2 (ethylene glycol).
Discoloration of the solution will occur (from violet to colorless).
