A) 0
B) 1.7 3BM
C) 2.83 BM
D) 4.9 BM
Correct Answer: D
Solution :
The spin only magnetic moment of\[{{[Cr{{F}_{6}}]}^{4-}}\] \[x-6=-4\] \[x=+\,2\] \[Cr(+2)=[Ar]\,\,3{{d}^{4}}\] \[n=4\](number of unpaired electrons) Magnetic moment \[=\sqrt{n(n+2)}=\sqrt{4(4+2)}\] \[=\sqrt{24}\] \[=4.9\,BM\]You need to login to perform this action.
