Question

Write the observation and name of the product for the following:
(i) When ethene is passed in bromine solution in CCl₄.
(ii) When Baeyer's reagent reacts with ethene.

Answer 1

(i) When ethene is passed through bromine solution in CCl_​4, the orange colour of bromine slowly disappears and decolourised ethylene bromide is formed as a product.



(ii) When Bayer's reagent (dilute or alkaline solution of potassium permanganate) reacts with ethene, its purple colour gets discharged slowly. The product formed is 1,2-ethanediol, which is colourless.
