Solution

## The correct option is B Statement 1 is true, statement 2 is true, statement 2 is not the correct explanation for statement 1(1) The electronic configuration of Mn2+=[Ar]3d5 Cr3+=[Ar]3d3 V3+=[Ar]3d2 Ti3+=[Ar]3d1 So number of unpaired electrons in Mn2+,Cr3+,V3+and Ti3+ are 5, 3, 2 and 1 respectively. (2) The magnetic moment can be calculated by the formula, [(n)(n+2)]12, where n = number of unpaired electrons. Thus magnetic moment of V3+ is 812 BM
