Vedclass · Answer

(C) To determine if an ion is paramagnetic,we check for the presence of unpaired electrons in its electronic configuration:$1. Cu^{+} (Z=29): [Ar] 3d^{10} 4s^{0}$. All electrons are paired,so it is diamagnetic.$2. Zn^{2+} (Z=30): [Ar] 3d^{10} 4s^{0}$. All electrons are paired,so it is diamagnetic.$3. Ti^{3+} (Z=22): [Ar] 3d^{1} 4s^{0}$. It has one unpaired electron in the $3d$ orbital,making it paramagnetic.$4. Ti^{4+} (Z=22): [Ar] 3d^{0} 4s^{0}$. It has no electrons in the $d$ orbital,so it is diamagnetic.Therefore,the correct option is $(C)$.
