White phosphorus, when heated with conc. solution in an inert atmosphere of , forms phosphine and a sodium salt of oxoacid of phosphorus, . The oxidation state of phosphorus in is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
White phosphorus reacts with conc. NaOH to form phosphine and sodium hypophosphite. P4 + 3NaOH +H2O → PH3 + NaH2PO2 The oxidation state of phosphorus will be : +1+2+X-4=0X =+1
