Question

Which reagent used to test unsaturation of alkenes? (A) conc. H2SO4 (B) Solution of Br2 in CCl4 (C) Ammonical Cu2Cl2 (D) Ammonical AgNO3

Tardigrade Admin · Accepted Answer

Solution of bromine in carbon tetrachloride is used to test for unsaturation of alkene. The reddish brown colour of bromine disappears due to the formation of colourless dibromo ethane (.C2H4Br2.) .
