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 NCH 2 CH 2 NH 2 ; atomic numbers : Ti = 22; Cr = 24; Cp = 27; Pt = 78}
List-I | List-II | ||
P. | [Cr(NH3)4Cl2)Cl] | 1. | Paramagnetic and exhibits ionisation isomerism |
Q. | [Ti(H2O)5Cl](NO3)2 | 2. | Diamagentic and exhibits cis-trans isomerism |
R. | [Pt(en)(NH3)Cl]NO3 | 3. | Paramagentic and exhibits cis-trans isomerism |
S. | [Co(NH3)4(NO3)2]NO3 | 4. | Diamagentic and exhibits ionisation isomerism |

(P) | [Cr(NH3)4Cl2]Cl | Cr+3 is d3. It is paramagnetic and it shows cis-trans isomerism. |
(Q) | [Ti(H2O)5Cl](NO3)2 | Ti+3 is d1. It is paramagnetic and it show ionisation isomerism. |
(R) | [Pt(en)(NH3)Cl]NO3 | Pt+2 is d8. But this complex is square planar and all electron are paired. So it is diamagnatic. It exhibit ionisation isomerism. |
(S) | [Co(NH3)4(NO3)2]NO3 | Co+3 is d6. Since ligands are strong, so electron are paired. It is diamagnetic. It exhibit cis-trans isomerism. |
