Question

How to do bromine water test??????

Answer 1

Answer:

The bromine water test is a qualitative test, used to identify the alkene or alkane functional groups present in the compound. Alkene groups react with bromine water in the dark condition and undergo an addition reaction, to give a decolourized solution. On the other hand, alkane doesn’t react with bromine water and the colour of the bromine water remains the same. Enols, alkenes, aniline, glucose, phenols and acetyl groups are the most common compounds to undergo bromine water test. The test also identifies the presence of an aldehyde group in the compound. During the process, the colour of the bromine water changes from yellow to colourless.
