Question

Which of the following is a disproportionation reaction? (A) Cl2(g) + 2OH-(aq) → ClO-(aq) + Cl-(aq) + H2O(l) (B) Cl2(g) + 2I- (aq) → 2Cl- (aq) + I2(s) (C) 2Fe(s) + 3H2O(l) xrightarrowΔ Fe2O3(s) + 3H2(g) (D) 2H2O(l) + 2F2(g) → 4HF(aq) + O2(g)

Q. Which of the following is a disproportionation reaction?

$C l_{2 (g)} + 2 O H_{(a q)}^{-} \to Cl O_{(a q)}^{-} + C l_{(a q)}^{-} + H_{2} O_{(l)}$

$C l_{2 (g)} + 2 I_{(a q)}^{-} \to 2 C l_{(a q)}^{-} + I_{2 (s)}$

$2 F e_{(s)} + 3 H_{2} O_{(l)} Δ F e_{2} O_{3 (s)} + 3 H_{2 (g)}$

$2 H_{2} O_{(l)} + 2 F_{2 (g)} \to 4 H F_{(a q)} + O_{2 (g)}$

Chlorine is simultaneously reduced and oxidised.

Q. Which of the following is a disproportionation reaction?

Cl2(g)​+2OH(aq)−​→ClO(aq)−​+Cl(aq)−​+H2​O(l)​

Cl2(g)​+2I(aq)−​→2Cl(aq)−​+I2(s)​

2Fe(s)​+3H2​O(l)​Δ​Fe2​O3(s)​+3H2(g)​

2H2​O(l)​+2F2(g)​→4HF(aq)​+O2(g)​

Chlorine is simultaneously reduced and oxidised.

$C l_{2 (g)} + 2 O H_{(a q)}^{-} \to Cl O_{(a q)}^{-} + C l_{(a q)}^{-} + H_{2} O_{(l)}$

$C l_{2 (g)} + 2 I_{(a q)}^{-} \to 2 C l_{(a q)}^{-} + I_{2 (s)}$

$2 F e_{(s)} + 3 H_{2} O_{(l)} Δ F e_{2} O_{3 (s)} + 3 H_{2 (g)}$

$2 H_{2} O_{(l)} + 2 F_{2 (g)} \to 4 H F_{(a q)} + O_{2 (g)}$
