Solution

The correct options are
A $B r^{-}$
B $N O_{3}^{-}$
C $N O_{2}^{-}$
Reddish brown gas is obtained when $B r^{-}$ , $N O_{3}^{-}$ and $N O_{2}^{-}$ are treated with conc. $H_{2} S O_{4}$ .
$K B r + H_{2} S O_{4} Δ - \to K_{2} S O_{4} + 2 H B r ↑$
$2 N a N O_{2} + H_{2} S O_{4} \to N a_{2} S O_{4} + 2 H N O_{2}$
$3 H N O_{2} \to H N O_{3} + 2 N O ↑ + H_{2} O$
$2 N O + O_{2} \to 2 N O_{2}$
$N a N O_{3} + H_{2} S O_{4} \to N a H S O_{4} + H N O_{3}$
$4 H N O_{3} \to 4 N O_{2} ↑ + O_{2} ↑ + 2 H_{2} O$
