Magnetic moment of Cr^(+2)(Z=24),Mn^(+2)...

Magnetic moment of `Cr^(+2)(Z=24),Mn^(+2)(Z=25)` and `Fe^(2+) (Z=26)` are x,y,z. they are in order

A

`x lt y lt z`

B

` x gt y gt z`

C

`z gt x =y`

D

`x=z lt y`

Text Solution

Verified by Experts

The correct Answer is:
D
`n , Cr^(2+)[Ar]3d^(5)`, so `n=4`, `Mn^(2+)[Ar]3d^(5)` so `n=5`, `Fe^(2+)[Ar]3d^(5)` so `n=4`
`n=` Number of unpaired electrons(s).

Magnetic moment of Cr(Z=24), Mn^+(Z=25) and Fe^(2+)(Z=26) are x,y,z. They are in order

Transition metals and many of their compounds show paramagnetic behaviour where there are unpaired electron or electrons. The magnetic moment arises from the spin and orbital motions in ions or molecule. Magnetic moment of n unpaired electrons is given as mu=sqrt(n(n+2)) Bohr magneton Magnetic moment increases as the number of unpaired electrons increases. Q. Magnetic moments of Cr(Z=24),Mn^(o+)(Z=35) and Fe^(2+)(Z=36) are x,y and z respectively. Which of the following order is correct?

Magnetic moment of V(Z = 23),Cr(Z = 24),and Mn(Z= 25) are x,y,z repectively hence

Magnetic moments of V(Z = 23), Cr(Z = 24), Mn (Z = 25) are x,y,z. HencE:

If Hind's rule is not followed , magnetic moment of Fe^(2+) , Mn^(+) and Cr all having 24 electron will be in order

Use the EAN rule to predict the molecular formula for the simple carbonyls of (a) Cr(Z = 24) (b) Fe (Z =26) and (c ) Ni (Z =28) (Assume that the oxidation state of the metals in the these carbonyls is zero) .
