The reaction of concentrated $HNO_3$ with phenol forms:

What product is formed when phenol reacts with dilute $HNO_3$?

When phenol reacts with dilute nitric acid at room temperature,the major product obtained is

Cumene on oxidation in air gives a compound,$X$. This on reaction with dilute acid gives $Y$ and $Z$. $Y$ reacts with sodium metal and not $Z$. What is $Z$ ?

Which among the following compounds has the highest melting point?

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: $\xrightarrow{Br_2, H_2O} \text{Product}$
