Match List I with List II
Choose the correct answer from the options given below: |
A-II, B-IV, C-I, D-III A-I, B-III, C-II, D-IV A-I, B-IV, C-III, D-II A-II, B-IV, C-III, D-I |
A-II, B-IV, C-I, D-III |
The correct answer is option 1. A-II, B-IV, C-I, D-III. A. \(V^{2+}\): Number of unpaired electrons = 3 So the magnetic moment will be \(\mu = \sqrt{n (n + 2)}\) or, \(\mu = \sqrt{3 (3 + 2)}\) or, \(\mu =\sqrt{15}\) or, \(\mu = 3.87\) Which matches with II from List II. B. \(Ni^{2+}\)
Number of unpaired electrons = 2 So the magnetic moment will be \(\mu = \sqrt{2 (2 + 2)}\) or, \(\mu =\sqrt{8}\) or, \(\mu = 2.84\) Which matches with IV from List II. C. \(Cu^{2+}\)
Number of unpaired electrons = 1 So the magnetic moment will be \(\mu = \sqrt{1 (1 + 2)}\) or, \(\mu =\sqrt{5}\) or, \(\mu = 1.73\) Which matches with I from List II. D. \(Cr^{2+}\) Number of unpaired electrons = 4 So the magnetic moment will be \(\mu = \sqrt{4 (4 + 2)}\) or, \(\mu =\sqrt{24}\) or, \(\mu = 4.90\) Which matches with III from List II. |
