How do alkenes decolourise bromine water?
By electrophilic addition to give the halohydrin,
Electrophiles or potential electrophiles react with olefins, a species rich in electrons:
The bromine's brown hue would fade, becoming nearly colorless.
Considering the intermediate steps, then:
Instead of A levels, this is at a first- or second-year level.

Alkenes decolourise bromine water through an addition reaction, where bromine adds across the carbon-carbon double bond, breaking it and forming a colorless solution.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
