What is the structure of the major product when phenol is treated with bromine water?     JEE Main  Online Paper (Held On 22 April 2013)

A)          

B)  

C)  

D)  

Correct Answer: A

Solution :

 Phenol has activating (electron releasing) \[-\text{OH}\]group and bromine water supplies \[\text{B}{{\text{r}}^{+}}\]ion easily, hence under such conditions reaction does not stop at monobromo or dibromo stage but a fully brominated (2,4,6,-tribromophenol) compound is the final product.
