Vedclass · Answer

(D) The reaction in option $D$ produces ethene $(C_2H_4)$,which is an unsaturated hydrocarbon containing a carbon-carbon double bond.Unsaturated hydrocarbons undergo addition reactions with bromine,which results in the decolourisation of the reddish-brown bromine water.This is a standard test for the detection of unsaturation in organic compounds.The reaction is: $C_2H_5OH \xrightarrow[443 \ K]{H^{+}} CH_2=CH_2 + H_2O$.
