Bomine/water reacts with phenol and decolorize orange colour and turns it to which of the coloured precipitate?
Correct answer: A. White precipitate
- A. White precipitate
- B. Pink precipitate
- C. Blue precipitate
- D. Black precipitate
Explanation
When bromine water reacts with phenol, it forms a white precipitate known as 2,4,6-tribromophenol. This white precipitate is formed due to the substitution of hydrogen atoms in phenol by bromine atoms. The presence of this white precipitate indicates the reaction between bromine water and phenol. The other options are incorrect because they mention different colored precipitates which do not form as a result of this specific reaction.
