C - rst
D- prst
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....
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
