`{:("P","Q","R","S"),(2,1,3,4):}`
`{:("P","Q","R","S"),(1,3,4,2):}`

Solution :P : `Cr^(3+)` has `3d^(3)` configuration with 3 unpaired electrons. Hence,it shows PARAMAGNETIC behaviour. Complex of the type `MA_(4)B_(2)`shows cis-trans isomerism.
Q : `Ti^(3+)` has `3d^(1)` configuration with 1 unpaired electron. Hence, it is paramagnetic. Complex gives `Cl^(-)` and `NO_(3)^(-)`ions in solution. Hence, it shows ionisation isomerism.
R : `Pt^(2+)` has `3d^(8)` configuration but ligands are strong field ligands. Hence, all electrons pair up. Hence, it is diamagnetic and FORMS square planar complex. It also shows ionisation isomerism.
S : `Co^(3+)` has `3d^(6)` configuration. But ligands present are strong enough to CAUSE electron pairing. Hence, it will be diamagnetic. As it is a complex of the type `MA_(4)B_(2)`, it exhibits cis-trans isomerism.

c.`{:(P , Q , R , S), (2 , 1 , 3 , 4):}`
d.`{:(P , Q , R , S), (1 , 3 , 4 , 2):}`

Solution :`P : Cr^(3+)` has `3d^(3)` configuration with 3 UNPAIRED electrons . Hence , it shows paramagnetic behaviour . Complex of the type `Ma_(4)b_(2)` shows cis-trans isomerism .
`Q: Ti^(3+)` has `3d^(1)` configuration , hence shows paramagnetic behaviour . complex GIVES `Cl^(-)` and `NO_(3)^(-)` ions in solution hence , shows ionisation isomerism .
R : `Pt^(2+)` has `3d^(8)` configuration but ligands are strong field ligands hence it forms square PLANAR complex . Thus , all electrons are paired and it also exhibits ionisation isomerism .
S : `CO^(3+)` has `3d^(6)` configuration . But , ligands present are strong enough to CAUSE electron pairing , hence , it shows diamagnetic behaviour and exhibits cis-trans isomerism as it is `Ma_(4) b_2` type complex .
