Due to resonance,the oxygen atom of the $-OH$ group in phenol:

What are $X$ and $Y$ respectively in the following set of reactions?

Hybridisation shown by Carbon and Oxygen of $-OH$ group in phenol are respectively . . . . . . .

Identify the incorrect statement from the following.

Which of the following is the most acidic compound?

The reactant is $4-hydroxy-3-methylbenzenesulfonic acid$. The reaction with $Br_2$ in $H_2O$ (bromine water) is an electrophilic aromatic substitution. The $-OH$ group is strongly activating and ortho/para directing. The $-SO_3H$ group is a good leaving group in the presence of excess bromine water. Predict the product of the reaction: $\xrightarrow{Br_2, H_2O} \text{Product}$
