Select the correct option, among $$Sc(III),\ Ti(IV),\ Pd(II)$$ and $$Cu(II)$$ ions.

AAll are paramagnetic
BAll are diamagnetic
C$$Sc(III),\ Ti(IV)$$ are paramagnetic and $$Pd(III),\ Cu(II)$$ are diamagnetic
DSc(III), Ti(IV) are diamagnetic and Pd(II), Cu(II) are paramagnetic
Correct Answer

Solution

$${ SC }^{ 3+ }\left( { [Ar]3d }^{ 0 } \right) $$ ] $$\rightarrow $$ since no unpaired electrons so diamagnetic $${ Ti }^{ 4+ }\left([Ar] { 3d }^{ 0 } \right) $$ ] $$\rightarrow $$ since no unpaired electrons so diamagnetic $${ Pd }^{ 2+ }\left( [Kr]{ 4d }^{ 8 } \right) $$ ] $$\rightarrow $$ since there is unpaired electrons so paramagnetic $${ Cu }^{ 2+ }\left([Ar] { 3d }^{ 9 } \right) $$ ] $$\rightarrow $$ since there is unpaired electrons so paramagnetic. So, the correct option is D.
