Question

Match Column I and Column II

Answer 1

(A) : ${Co}^{2+}\left(aq\right)$ is pink/light pink in color and forms outer orbital complex and its magnetic moment is $\sqrt{3(3+2)}=\sqrt{15}BM$ as it contains 3 unpaired electrons.

(B) : ${Mn}^{2+}\left(aq\right)$ is pink/light pink in color and is paramagnetic in nature due to presence of 5 unpaired electrons in presence of weak field ligand.

(C) : $V^{2+}\left(aq\right)$ is purple in color and is paramagnetic in nature due to presence of 3 unpaired electrons.

(D) : ${Ti}^{3+}\left(aq\right)$ is purple in color and forms inner orbital complexes and its magnetic moment is $\sqrt{1(1+2)}=\sqrt{3}BM$.It is also paramagnetic in nature due to presence of one unpaired electron.
