Question

Match each coordination compound in List-I with an appropriate of characteristics from List-II. ($en=H_{2}HC{H}_{2}C{H}_{2}N{H}_2$; Atomic numbers: Ti = 22, Cr = 24; Co = 27; Pt = 78)

	List I		List II
A	$\left[Cr{\left({NH}_3\right)}_4{Cl}_2\right]Cl$	1	Paramagnetic and exhibits ionization isomerism
B	$\left[Ti{\left(H_{2}O\right)}_{3}Cl\right]{\left({NO}_3\right)}_2$	2	Diamagnetic and exhibits cis-trans isomerism
C	$\left[Pt\left(en\right)\left(N{H}_3\right)Cl\right]{NO}_3$	3	Paramagnetic and exhibits cis-trans isomerism
D	$\left[Co{\left({NH}_3\right)}_4{\left({NO}_3\right)}_2\right]{NO}_3$	4	Diamagnetic and exhibits ionization isomerism

Answer 1

$A\to C{r}^{+3}\Rightarrow x=2=+1\Rightarrow x=3$

$B\to T{i}^{+3}\Rightarrow x-1=2\Rightarrow x=3$

$C\to P{t}^{+4}\Rightarrow x-2-1=1\Rightarrow x=4$

$d\to C{o}^{+3}\Rightarrow x-2=1\Rightarrow x=3$

$A\to 2$

$B\to 1$

$C\to 1$

$D\to 2$

$H_{2}O$ is weak ligand.
