Question
On heating with concentrated \[\ce{NaOH}\] solution in an inert atmosphere of \[\ce{CO2}\], white phosphorus gives a gas. Which of the following statement is incorrect about the gas?
Options
It is highly poisonous and has smell like rotten fish.
It’s solution in water decomposes in the presence of light.
It is more basic than \[\ce{NH3}\].
It is less basic than \[\ce{NH3}\].
Solution
It is more basic than \[\ce{NH3}\].
Explanation:
When heated with concentrated \[\ce{NaOH}\] in an inert \[\ce{CO2}\] environment. It forms
\[\ce{PH3P4 + 3NaOH + 3H2O -> PH3 + 3NaH2PO2}\]
As we progress from the top to the bottom in a group, the basic character of hydrides reduces \[\ce{PH3}\] is basic than NH3.
