When aqueous bromine is shaken with cyclohexane and allowed to stand, two layers form. The top cyclohexane layer is coloured and the bottom aqueous layer is almost colourless. What is the most likely explanation for this observation?
ABromine is reduced to bromide ions in the bottom layer.
BBromine molecules are non-polar.
CBromine reacts with water but cannot react with cyclohexane.
DThe product of the reaction between bromine and cyclohexane is coloured.
✓ Correct answer
B: Bromine molecules are non-polar.
