$ScCl_3$

Vedclass · Answer

(B) Substances that are diamagnetic are repelled by a magnetic field,causing them to appear to weigh less when weighed in such a field.$ScCl_3$ dissociates as: $ScCl_3 	o Sc^{3+} + 3Cl^-$.The electronic configuration of $Sc^{3+}$ is $[Ar] 3d^0 4s^0$.Since there are no unpaired electrons,$Sc^{3+}$ is diamagnetic.Therefore,$ScCl_3$ is repelled by the magnetic field and weighs less.
