A) \[CO_{3}^{2-},SO_{3}^{2-}\] and \[BO_{3}^{2-}\]
B) \[ASO_{3}^{3-},ClO_{3}^{-}\] and \[SO_{3}^{2-}\]
C) \[NO_{3}^{-},CO_{3}^{2-}\] and \[BO_{3}^{3-}\]
D) \[SO_{3}^{2-},NO_{3}^{-}\] and \[BO_{3}^{3-}\]
Correct Answer: B
Solution :
\[-nF{{E}^{\circ }}_{cell}=-RT\], \[{{E}^{\circ }}_{cell}=\frac{RT}{nF}\] and \[{{E}^{\circ }}_{cell}\] have \[=\frac{1}{2}\frac{RT}{F}\] hybridisation and hence are planar species while \[\begin{align} & N{{H}_{4}}Cl\xrightarrow{\Delta }N{{H}_{3}}+HCl \\ & ABC \\ \end{align}\] and \[\begin{align} & N{{H}_{3}}+HCl\to N{{H}_{4}}Cl \\ & \text{Bwhite fumes} \\ \end{align}\] have \[\begin{align} & N{{H}_{3}}+2{{K}_{2}}\left[ Hg{{I}_{4}} \right]+3KOH\to \\ & B\text{Nessler }\!\!'\!\!\text{ sreagent} \\ \end{align}\] hybridisation and hence are planar species
