Question

Match each coordination compound in List-I with an appropriate pair of characteristics from List-II and select the correct answer using the code given below the lists $\{en=H_{2}NC{H}_{2}C{H}_{2}N{H}_2;$ atomic numbers: $Ti=22,Cr=24;Co=27;Pt=78)$

List - I		List - II
P	$\left[Cr{\left(N{H}_3\right)}_{4}C{l}_2\right]Cl$	1	Paramagnetic and exhibits ionization isomerism
Q	$\left[Ti{\left(H_{2}O\right)}_{5}Cl\right]{\left(N{O}_3\right)}_2$	2	Diamagnetic and exhibits cis-trans isomerism
R	$\left[Pt(en)\left(N{H}_3\right)Cl\right]N{O}_3$	3	Paramagnetic and exhibits cis-trans isomerism
S	$\left[Co{\left(N{H}_3\right)}_4{\left(N{O}_3\right)}_2\right]N{O}_3$	4	Diamagnetic and exhibits ionization isomerism

• A. P - (4) , Q - (2) , R -(3) , S - (1)
• B. P - (3) , Q - (1) , R -(4) , S - (2)
• C. P - (2) , Q - (1) , R -(3) , S - (4)
• D. P - (1) , Q - (3) , R -(4) , S - (2)

Answer 1

Answer: (B)

(P) $\left[Cr{\left(N{H}_3\right)}_{4}C{l}_2\right]Cl⟶$ Paramagnetic and exhibits cis-trans isomerism
(Q) $\left[Ti{\left(H_{2}O\right)}_{5}Cl\right]{\left(N{O}_3\right)}_2⟶$ Paramagnetic and exhibits ionization isomerism
(R) $\left[Pt(en)\left(N{H}_3\right)Cl\right]N{O}_3⟶$ Diamagnetic and exhibits ionization isomerism
(S) $\left[Co{\left(N{H}_3\right)}_4{\left(N{O}_3\right)}_2\right]N{O}_3⟶$ Diamagnetic and exhibits cis-trans isomerism
