It is more basic than NH₃ is the incorrect option.
Explanation:
- The reaction between the white phosphorus and sodium hydroxide gives a gas.
- The reaction is
- P4 + NaOH + H20 = PH3 + NaH2PO2.
- Here in the reaction we can see that the gas produced is phosphine.
- This gas is having a similar structure to that of ammonia.
- But in case of nitrogen, it doesn't have a free d orbital like phosphorous.
- So in phosphorous, the electrons can freely move to d orbitals, and the Electron density of phosphorous lone pair is much less.
- Both ammonia and phosphine being a Lewis base, needs to have lone pari to be a base.
- So the statement that phosphine is more basic than NH₃ is false.
