White phosphorus reacts with caustic soda. The products are $PH_3$ and $NaH_2PO_2$. This reaction is an example of

For the given reaction $Cl_2 + OH^{-} \to ClO^{-} + Cl^{-}$,select the correct sequence of $T$ (True) and $F$ (False) for the following statements:
$(1)$ The given reaction occurs in a basic medium.
$(2)$ $Cl_2$ undergoes both oxidation and reduction.
$(3)$ The reaction is a disproportionation reaction.
$(4)$ The oxidation state of $Cl$ in $ClO^{-}$ is $+1$.

Assign $A$,$B$,$C$,$D$ from the given type of reaction.
$P_4 + 3NaOH + 3H_2O \longrightarrow PH_3 + 3NaH_2PO_2$
