S-1 : `[Cr(NH_(3))_(6)]^(3+)` is a inner orbital complex with
S-2: The complex formed by joining the CN ligands to `Fe^(3+)` ion has theoretical value fo 'spin only' magnetic moment equal to 1.73 B.M.
S-3: `Na_(2)S+Na_(2)[Fe(CN)_(5)NO]rarrNa_(4)[Fe(CN)_(5)NOS],` In reactan and product the oxidation states of iron are same

Options

A. FTF
B. TTF
C. TTT
D. FFF

Answer

C

Explanation

`[Cr(NH_(3))_(6)]^(3+) implies d^(3) , t_(2 g )^( 2 ,2 , 1) eg^(0 , 0)`
CFSE = `-0.4 xx 3 Delta_(0) = -1.2 Delta_(0)`.
