Passage / Comprehension

When a substance undergoes nucleophilic substitution reaction and the nucleophile is the solvent itself, then the reaction is known as solvolysis. In solvolysis reaction, if the solvent used is water then the reaction is called as hydrolysis.

Which of the following show disproportionation redox reaction in hydrolysis.

Options:

Answer:

Solution:

Disproportionation involves an element being simultaneously oxidized and reduced.

For N₂O₄ hydrolysis:

$3 N_{2} O_{4} + 3 H_{2} O ⟶ 2 HNO_{3} + 4 HNO_{2}$

Nitrogen's oxidation state changes from +4 to +5 (in HNO₃) and +3 (in HNO₂).

For H₄P₂O₆ hydrolysis:

$2 H_{4} P_{2} O_{6} + 2 H_{2} O ⟶ 3 H_{3} PO_{4} + H_{3} PO_{3}$

Phosphorus's oxidation state changes from +4 to +5 (in H₃PO₄) and +3 (in H₃PO₃).
