`{:(,"Transition Metal","Magnetic moment(B.M)"),(,(A)"Titanium (III)",(1) 4:9),(,(B)"Vandium (II)",(2) 1.73),(,(C )"Iron (II),(3)3.87):}`

A

A-2,B-3,C-1

B

A-1,B-3,C-2

C

A-3,B-1,C-2

D

C-1,B-3,C-2

Text Solution

Verified by Experts

The correct Answer is:
A
`mu=sqrt(n(n+2))`,(n=no. of unpaired electrons)
(a) `mu=sqrt(n(n+2))`, (n= no. of unpaired electrons )
`Ti^(3+) to [Ar]3d^(1),mu=sqrt(1(1+2))=sqrt(3)=1.73 BM`
`V^(2+) to [Ar]3d^(3),mu=sqrt(3(3+2))=sqrt(15)=3.87 BM`
`Fe^(2+) to [Ar]3d^(4),mu=sqrt(4(4+2))=sqrt(24)=4.89 BM`
