The substance(s) which disproportionate(s) in alkaline medium is/are
Options:(select one or more)
Answer:
A, B, D
Solution:
F₂ is the strongest oxidising agent and cannot be oxidised, so with alkali it only oxidises (giving OF₂ or O₂) - no disproportionation. Cl₂ → Cl⁻ + ClO⁻ (cold); 3Br₂ + 6NaOH(hot) → 5NaBr + NaBrO₃ + 3H₂O; P₄ + 3NaOH + 3H₂O → PH₃ + 3NaH₂PO₂.
