Heating benzoic acid with $X$ and phenol with $Y$ gives benzene. $X$ and $Y$ are respectively:

Match the following reactions of phenol with their products:

The major product of the following reaction sequence is:
Aniline $\xrightarrow[(i) NaNO_2, HCl, 273-278K]{(ii) H_2O, warm} \text{Product}$ $\xrightarrow[(iv) NaOH]{(iii) Br_2, (excess)} \text{Product}$ $\xrightarrow{(v) CH_3I} \text{Final Product}$

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

The phenolic group can be identified by a positive:

In the reaction shown below,$Y$ is:
