A) 4
B) 1
C) 2
D) 3
Correct Answer: A
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.
