STD 11 - 5. Thermodynamics and thermochemistry — NEET STD 11 Science — Question

Statement I : $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right]^{3+}$ is a homoleptic complex whereas $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right]^{+}$is a heteroleptic complex.

Statement II : Complex $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right]^{3+}$ has only one kind of ligands but $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right]^{+}$has more than one kind of ligands.

In the light of the above statements, choose the correct answer from the options given below.

$\begin{align}
   \begin{matrix}
   C{{H}_{3}}-CH-C{{O}_{2}}H  \\
   |\,\,\,\,\,\,\,\,  \\
   \underset{\oplus }{\mathop{N}}{{H}_{3}}  \\
\end{matrix}\,\,\,\,\,\,p{{K}_{a}}=2.2 \\ 
  \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,p{{K}_{b}}=4.4 \\ 
\end{align}$
