Reaction of aniline with bromine water at room temperature produces a white precipitate of

2, 4, 6

- tribromoaniline, this on reaction with nitrous acid produces diazonium salt. In aniline, the maximum electron density is found at ortho- and parapositions of the

- N H_{2}

group. The

- N H_{2}

group is ortho and para directing and is a powerful activating group.

Q. Identify $X, Y$ and $Z$ in the given sequence of reactions.

$X = H B r; Y = N a N O_{2} + H Cl; Z =$ heat

$X - B r_{2} / CC l_{4}; Y = H N O_{2}; Z = C H_{3} O H$

$X = B r_{2} / C u B r; Y = N a N O_{2} + H Cl; Z = N a O H$

$X = B r_{2} (a q .); Y = N a N O_{2} + H Cl (0 - 4^{\circ} C); Z = H_{3} P O_{2} + H_{2} O$

Q. Identify X,Y and Z in the given sequence of reactions.

X=HBr;Y=NaNO2​+HCl;Z= heat

X−Br2​/CCl4​;Y=HNO2​;Z=CH3​OH

X=Br2​/CuBr;Y=NaNO2​+HCl;Z=NaOH

X=Br2​(aq.);Y=NaNO2​+HCl(0−4∘C);Z=H3​PO2​+H2​O
