It is given that a complex formed by one Ni 2+ ion and some Cl – ions and some PPh 3 molecules does not show geometrical isomerism and its solution does not show electrical conductance. Then which is correct about the complex : (a) It is square planar (b) It is tetrahedral (c) It is diamagnetic (d) none of the above is correct

hey student..
here you need to try using the information given in the question and to correlate that to the options given
for example, it says the complex does not show geometrical isomerism, so try arranging the ligands in such a way that there should be no optical activity in the molecule, also a similar conclusion can be quoted from the electrical properties whether the compound is diamagnetic or paramagnetic
