In a laboratory experiment, students burned methane (CH₄) in the presence of oxygen and observed that carbon dioxide and water were formed with the release of heat and light.

A saturated organic compound 'A' belongs to the homologous series of alcohols. On heating 'A' with concentrated sulphuric acid at 443 K, it forms an unsaturated compound 'B' with molecular mass 28 u. The compound 'B' on addition of one mole of hydrogen in the presence of Nickel, changes to a saturated hydrocarbon 'C'.

With the help of diagram, show the formation of micelles, when soap is applied on oily dirt.
