Which of the following will be able to show geometrical isomerism?
1 \(\mathrm{MA}_2 \mathrm{~B}_2\) - Tetrahedral
2 MABCD - Tetrahedral
3 \(\mathrm{MA}_3 \mathrm{~B}\) - Square planar
4 MABCD - Square planar
Explanation:
(d) Tetrahedral complexes do not show geometrical isomerism because due to symmetrical structure, relative positions of the ligands is same with respect to each other.
Square planar complexes of the type \(\mathrm{Ma}_3 \mathrm{~B}\) do not show geometrical isomerism because the possible spatial arrangements are equivalent.
MABCD type square planar complexes show three isomers which can be obtained by fixing the position of one ligand and placing any of the remaining three ligands at the trans position one by one.

In Which one of the pairs of ion given, there is an ion that forms a coordination compound with both aqueous sodium hydroxide and ammonia and an other ion that forms a coordination compound only with aqueous sodium hydroxide?
1 \(\mathrm{Pb}^{2+}, \mathrm{Cu}^{2+}\)
2 \(\mathrm{Zn}^{2+}, \mathrm{Al}^{3+}\)
3 \(\mathrm{Cu}^{2+}, \mathrm{Zn}^{2+}\)
4 \(\mathrm{Al}^{3+}, \mathrm{Cu}^{2+}\)
Explanation:
(b)\(\mathrm{Zn}^{2+}\) ion reacts with aq. NaOH and \(\mathrm{NH}_3\) and forms a coordination compound.
\(\mathrm{Zn}^{2+}+4 \mathrm{NaOH} \rightarrow\left[\mathrm{Zn}(\mathrm{OH})_4\right]^{2-}+4 \mathrm{Na}^{+}\)
\(\mathrm{Zn}^{2+}+4 \mathrm{NH}_3 \rightarrow\left[\mathrm{Zn}\left(\mathrm{NH}_3\right)_4\right]^{2+}\)
But, \(\mathrm{Al}^{3+}\) ion reacts only with NaOH
