- A \(\mathrm{PH}_3, \mathrm{NaPO}_4\)
- B \(\mathrm{NaH}_2 \mathrm{PO}_4, \mathrm{P}(\mathrm{OH})_3\)
- C \(\mathrm{PH}_3, \mathrm{NaH}_2 \mathrm{PO}_2\)
- D \(\mathrm{P}_4 \mathrm{O}_{10}, \mathrm{Na}\)
Answer & Solution
Correct Answer
(C) \(\mathrm{PH}_3, \mathrm{NaH}_2 \mathrm{PO}_2\)
Step-by-step Solution
Detailed explanation
White phosphorus dissolves in boiling \(\mathrm{NaOH}\) solution (in a \(\mathrm{CO}_2\) atmosphere) to give phosphine \(\left(\mathrm{PH}_3\right)\) and sodium hypo-phosphate \(\left(\mathrm{NaH}_2 \mathrm{PO}_2\right)\).…
