C6H6 xrightarrow[H2SO4]HNO3 X xrightarrow[FeCl3]Cl2 Y . In the above sequence Y can be (A) 3-nitrochlorobenzene (B) 1-nitrochlorobenzene (C) 4-nitrochlorobenzene (D) none of these

(HNO3 + H2SO4) reagent is the agent for nitration in aromatic rings. HNO3 + 2H2SO4 → NO2+ + HSO4- + H3O+ —NO2 group is a meta directing group so chlorine atom goes to meta position of the ring.

Q. $C_{6} H_{6} H N O_{3} H_{2} S O_{4} X C l_{2} F e C l_{3} Y$ .
In the above sequence $Y$ can be

3-nitrochlorobenzene

1-nitrochlorobenzene

4-nitrochlorobenzene

none of these

$(H N O_{3} + H_{2} S O_{4})$ reagent is the agent for nitration in aromatic rings.
$H N O_{3} + 2 H_{2} S O_{4} \to N O_{2}^{+} + H S O_{4}^{-} + H_{3} O^{+}$
$— N O_{2}$ group is a meta directing group so chlorine atom goes to meta position of the ring.
