Conductivity experiments indicate that dichlorotetraamine-palladium (IV)chloride is composed of 3 moles of ions per mole of compound.However,only 2 moles of AgCl per mole of compound are precipitated rapidly when silver nitrate solution is added to a solution of the palladium compound.What is the probable structure of the complex ion?
A)octahedral
B)square planar
C)tetrahedral
D)linear
E)trigonal planar

The precipitation reaction suggests that two chloride ions are readily available for reaction with silver ions. This is consistent with a square planar structure where two chloride ions are adjacent to each other in the plane of the molecule, while the third chloride ion is situated on the perpendicular axis, which makes it less accessible for reaction. The conductivity experiment indicates the presence of three moles of ions, which is also consistent with a square planar structure, where there are four ligands around the central palladium ion, resulting in four ions in solution.
