Question

Match the reaction in list 1 with their type in list 2.

Answer 1

(A) $3Xe{F}_4\left(s\right)+6H_{2}O\left(l{)}^{\underset{disproportionation}{\overset{hydrolysis}{\to }}}Xe{O}_3\right(s)+2Xe(g)+\frac{3}{2}{O}_2(g)+12HF(aq)$
$Xe{O}_3$ acts as a powerful oxidising agent in aqueous solution.
$Xe{O}_3+6H^{+}+6e^{-}\to Xe+3H_{2}O$; $E^o=2.10V$
Xe is in elemental form.
$O_2$ acts as a ligand in various complexes.
(B) $S_2{O}_3^{2-}\left(aq\right)+2H^{+}\left(aq\right)\stackrel{disproportionation}{\to }S\left(s\right)+S{O}_2\left(g\right)+H_{2}O\left(l\right)$
$S{O}_2$ acts as an oxidising as well as a reducing agent.
S is in elemental form. $H_{2}O$ acts as a ligand in various complexes like $\left[Fe\right(H_{2}O{)}_6{]}_2^{+},\left[Co\right(H_{2}O{)}_6{]}_3^{+}$ etc.
(C) $N_2{O}_3\left(l\right)\underset{disproportionation}{\overset{0^{o}C}{\to }}NO\left(g\right)+N{O}_2\left(g\right)$
Blue liquid at about $100$${}^{o}C$. $NO$ acts as a ligand in many complexes like $\left[Fe\right(H_{2}O)5NO{]}^{2+},[Fe(CN{)}_{5}NO{]}^2$ etc.
(D) $2AgN{O}_3\to 2Ag\left(s\right)+2N{O}_2+O_2$
$N{O}_2$ acts as a ligand in co-ordination complex. $O_2$ is paramagnetic in nature.
