Vedclass · Answer

(C) $1$. When phenol is treated with concentrated $H_2SO_4$ at $100^{\circ}C$,the major product formed is $p$-phenolsulfonic acid $(A)$.$2$. When $p$-phenolsulfonic acid is treated with excess bromine water $(Br_2/H_2O)$,the $-SO_3H$ group is replaced by a bromine atom due to its high reactivity and the stability of the resulting $2,4,6$-tribromophenol product. This is an example of ipso substitution.$3$. Therefore,the end product $(B)$ is $2,4,6$-tribromophenol.

Identify the end product $(B)$ of the following sequence of reactions:
Phenol $\xrightarrow[100^{\circ}C]{\text{conc. } H_2SO_4} A$ $\xrightarrow{Br_2/H_2O \text{ (excess)}} B$
