Correct answer is (b) 3 I 2+6 OH - longrightarrow IO 3-+5 I -+3 H 2 O

Q. Which of the following reaction represents disproportionation?

$C u + 4 H N O_{3} \to C u (N O_{3})_{2} + 2 N O_{2} + 2 H_{2} O$

$3 I_{2} + 6 O H^{-} ⟶ I O_{3}^{-} + 5 I^{-} + 3 H_{2} O$

$C l_{2} + I_{2} ⟶ 2 I Cl$

$Z n + 2 H Cl ⟶ Z n C l_{2} + H_{2}$

Correct answer is (b) $3 I_{2} + 6 O H^{-} ⟶ I O_{3}^{-} + 5 I^{-} + 3 H_{2} O$

Q. Which of the following reaction represents disproportionation?

Cu+4HNO3​→Cu(NO3​)2​+2NO2​+2H2​O

3I2​+6OH−⟶IO3−​+5I−+3H2​O

Cl2​+I2​⟶2ICl

Zn+2HCl⟶ZnCl2​+H2​

Correct answer is (b) 3I2​+6OH−⟶IO3−​+5I−+3H2​O

$C u + 4 H N O_{3} \to C u (N O_{3})_{2} + 2 N O_{2} + 2 H_{2} O$

$3 I_{2} + 6 O H^{-} ⟶ I O_{3}^{-} + 5 I^{-} + 3 H_{2} O$

$C l_{2} + I_{2} ⟶ 2 I Cl$

$Z n + 2 H Cl ⟶ Z n C l_{2} + H_{2}$

Correct answer is (b) $3 I_{2} + 6 O H^{-} ⟶ I O_{3}^{-} + 5 I^{-} + 3 H_{2} O$
