A) \[4\]
B) \[1\]
C) \[2\]
D) \[3\]
Correct Answer: D
Solution :
Magnetic moment\[=\sqrt{n(n+2)}\] where, \[n=\]number of unpaired electrons Given\[\mu =\sqrt{15}\] \[\sqrt{15}=\sqrt{n(n+2)}\] \[15=n(n+2)\] \[{{n}^{2}}+2n-15=0\] \[(n+5)(n-37)=0\] \[n=3\] \[(\because \,\,n\ne -5)\]You need to login to perform this action.
