(A) The geometrical isomers are as follows:
So, this compound is paramagnetic.
(B) The geometrical isomers are as follows:
So, this compound is paramagnetic.
(B) The geometrical isomers are as follows
So, this compound is diamagnetic.
(C) The complex has no geometrical isomers.
It has an unpaired electron, so the compound is paramagnetic.
(D) Since
H2O is a weak field ligand, so the electrons do not get paired up and the compound is paramagnetic.
