A. Conc. H2SO4 B. Br2
c. NO_{2}^{+}
232-504_1.jpg
Reaction involved are
2NaBr + 2 H2SO4 + MnO2
(A)
→ Na2SO4 + MnSO4 + Br2 ↑ + 2 H2O
[B]
Brown fumes
and pungent smell
H2SO4 + HNO3HSO_{4}^{-}+ NO_{2}^{+}+ H2O
[C]

Bond order = 2 paramagnetic
4. (d) (P)
2PbO2 + 2H2SO4 \overset{Warm}{\rightarrow}2PbSO4 + 2H2O + 2H2O + O2
(Q)
Na2S2O3 + 5H2O + 4CI2 → 2NaHSO4 + 8HCI
(R) N2H4 + 2I2 → N2 + 4HI
(S) XeF2 + 2NO → Xe + 2NOF
