When aqueous bromine is shaken with cyclohexane and then left to settle, two separate layers appear. The upper cyclohexane layer becomes coloured, while the lower aqueous layer is almost colourless. What is the most likely reason 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.
