1well i dont see any problem with the solutions....
t) is given in all options becos splitting,stability factors r different for 4d from 3d....
\begin{matrix} \textup{Column I} & \textup{Column II} \\ \textup{(a) Stability of complex}&\textup{(p) Electronic configuration of metal/metal ion} \\ \textup{(b) shape of complex} & \textup{(q) chelation effect}\\ \textup{(c) crystal field splitting energy}& \textup{(r) type of ligand}\\ \textup{(d) magnetic behaviour of complex} & \textup{(s) oxidation state of metal}\\ & \textup{(t) type of metal atom} \end{matrix}
ans given

106@rickde; CFSE depends on chelation also naa? more chelation more is the value of CFSE .. it also depends on config of metal ion naa? for ex. Fe2+ and Fe3+
Magnetic behaviour: Chelation can bring about pairing also (atleast written in JD LEE)
1well u see if we go by NCERT...it mentions chelation only for stability....
and Fe+2 n Fe+3....changing oxidation state...its in the option.....i know see that S → P
also......R→Q....cos some ligands r strong bcos they chelate......
so type of ligand can also be related to chelation
sry i overlooked all these points
