Which of the following paramagnetic ions would exhibit a magnetic moment (spin only) of the order of 5 BM? (At. Nos. \[Mn=25,Cr=24,V=23,Ti=22\])     JEE Main  Online Paper (Held On 19  May  2012)

A) \[M{{n}^{2+}}\]                               

B)                        \[T{{i}^{2+}}\]

C)                        \[{{V}^{2+}}\]                                   

D)                        \[C{{r}^{2+}}\]

Correct Answer: D

Solution :

Hence \[C{{r}^{2+}}\]has magnetic moment of the order of 5 B.M.
