Identify the major product formed from the following reaction sequence:

When phenol is reacted with $NH_3$ in the presence of $ZnCl_2$,what is the product formed?

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

$A$ trisubstituted compound '$A$',$C_{10}H_{12}O_2$ gives a neutral $FeCl_3$ test positive. Treatment of compound '$A$' with $NaOH$ and $CH_3Br$ gives $C_{11}H_{14}O_2$,with hydroiodic acid $(HI)$ gives methyl iodide,and with hot conc. $NaOH$ gives a compound $B$,$C_{10}H_{12}O_2$. Compound '$A$' also decolorises alkaline $KMnO_4$. The number of $\pi$ bonds present in the compound '$A$' is $...........$

The reaction sequence is as follows:
$Catechol \xrightarrow{(i) CHCl_3 + KOH}{(ii) CH_2I_2 + NaOH} [X]$
Here $[X]$ is:

An organic compound $A$ with empirical formula $C_6H_6O$ gives a sooty flame on burning. Its reaction with bromine solution in a low polarity solvent results in a high yield of $B$. $B$ is:
