On heating with concentrated NaOH in an inert environment of CO 2, it forms PH 3 ⋅ P 4+3 NaOH +3 H 2 O arrow PH 3+3 NaH 2 PO 2. PH 3 is more basic than NH 3 as we move frrom top to to bottom in a group the basic nature of hydrides decreases.

Q. On heating with concentrated $N a O H$ solution in an inert atmosphere of $C O_{2}$ white phosphorous gives a gas. Which of the following statement is incorrect about the gas ?

It is less basic than $N H_{3}$

It is more basic than $N H_{3}$

It is highly poisonous and has smell like rotten fish.

It's solution in water decomposes in the presence of light

On heating with concentrated $N a O H$ in an inert environment of $C O_{2}$ , it forms $P H_{3} \cdot P_{4} + 3 N a O H + 3 H_{2} O \to P H_{3} + 3 N a H_{2} P O_{2}$ .
$P H_{3}$ is more basic than $N H_{3}$ as we move frrom top to to bottom in a group the basic nature of hydrides decreases.
