Bromine Water Test

Test for Unsaturation (Alkenes/Alkynes) and Activated Aromatic Rings (Phenols/Anilines).

1. Setup Experiment

Select Unknown Compound

2. Observation

Physical State Clear Liquid

Status: Standby.
Select an organic compound. The addition of reddish-brown aqueous Bromine (Br₂) will initiate an electrophilic attack if the compound is sufficiently reactive.

3. Chemical Principles

Alkenes/Alkynes: Undergo rapid electrophilic addition across the pi-bond. The colored Br₂ is consumed, making the solution colorless.

Phenols/Anilines: The -OH or -NH₂ groups strongly activate the aromatic ring, causing rapid electrophilic aromatic substitution, yielding a white precipitate.

Note: Saturated alkanes and stable benzene rings do not react without a catalyst or UV light.
