उत्तर

(i) When ethene is passed in bromine solution in CCI4, the orange colour of bromine disappears due to formation of colourless ethylene bromide.

\[\ce{CH2 = CH2 + Br2 -> CH2Br - CH2Br}\]

(ii) When Baeyer's reagent reacts with ethene, colour of potassium permanganate gets discharged in this reaction.

\[\ce{CH2 = Ch2 + H2O + O ->[25°C-30°C][KMnO] Ch2OH - CH2OH}\]
