The correct answer is:
$\mathrm{C}_2 \mathrm{H}_5 \mathrm{OH} \xrightarrow[443 \mathrm{~K}]{\mathrm{H}^{+}} \mathrm{C}_2 \mathrm{H}_4+\mathrm{H}_2 \mathrm{O}$
One of the product in this reaction is ethene, an unsaturated hydrocarbon. It decolourises bromine water.
Bromine solution is the classic test for the detection of unsaturation.
A few drops of bromine water to the test tube with the ethanol produce reddish-brown colour.
