Question
In what way can it be proved that $PH_3$ is basic in nature?
✓
Answer
$PH_3 $ reacts with acids like HI to form $PH_4$ I which shows that it is basic in nature.
$\text{PH}_3+\text{HI}\ \ \ \rightarrow \ \ \text{PH}_4\text{I}$
Due to lone pair of electrons on P atom, $PH_3$ is acting as a Lewis base in the above reaction.
$\text{PH}_3+\text{HI}\ \ \ \rightarrow \ \ \text{PH}_4\text{I}$
Due to lone pair of electrons on P atom, $PH_3$ is acting as a Lewis base in the above reaction.
