Vedclass · Answer

(B) The reaction is: $Mg_3N_2(s) + 6H_2O(l) \rightarrow 3Mg(OH)_2(s) \downarrow + 2NH_3(g) \uparrow$.Here,$P$ is $Mg(OH)_2$ and $Q$ is $NH_3$ gas.Excess $NH_3$ forms coloured complexes with transition metal ions like $Ni^{2+}$,$Cr^{3+}$,and $Cu^{2+}$ due to $d-d$ transitions.However,$Zn^{2+}$ has a $3d^{10}$ electronic configuration (no unpaired electrons),so the complex $[Zn(NH_3)_4]^{2+}$ is colourless.Therefore,the correct option is $B$.

$Mg_3N_2(s) + H_2O \xrightarrow{R.T.} P \downarrow + Q \uparrow$. Excess $Q$ gas does not form a coloured complex with:
