Q. Match List-I with List-II, match the gas evolved during each reaction. List-I List-II A (NH4​)2​Cr2​O7​Δ​ 1 H2​ B KMnO4​+HCl→ 2 N2​ C Al+NaOH+H2​O→ 3 O2​ D NaNO3​Δ​ 4 Cl2​ Choose the correct answer from the options given below :

(A) - (II), (B) - (III), (C) - (I), (D) - (IV)

(A) - (III), (B) - (I), (C) - (IV), (D) - (II)

(A) - (II), (B) - (IV), (C) - (I), (D) - (III)

(A) - (III), (B) - (IV), (C) - (I), (D) - (II)

(NH4​)2​Cr2​O7​Δ​N2​+Cr2​O3​+4H2​O KMnO4​+HCl→MnCl2​+KCl+Cl2​+H2​O Al+NaOH+H2​O→H2​+Na[Al(OH)4​] NaNO3​⟶NaNO2​+O2​

$(N H_{4})_{2} C r_{2} O_{7} Δ N_{2} + C r_{2} O_{3} + 4 H_{2} O$
$K M n O_{4} + H Cl \to M n C l_{2} + K Cl + C l_{2} + H_{2} O$
$A l + N a O H + H_{2} O \to H_{2} + N a [A l (O H)_{4}]$
$N a N O_{3} ⟶ N a N O_{2} + O_{2}$
