MCQ

Which statement is true for sodium nitro prusside?

A
$'NO-$ ligand' acts as cationic ligand.
B
$'Fe'$ present in $+2$ oxidation state
✓
It's used to give test of $S^{-2}$ ion
D
All of the above are correct

✓

Answer

Correct option: C.

It's used to give test of $S^{-2}$ ion

c
$EAN = Z - X + Y$

$Z =$ Atomic number of the metal

$X =$ Number of electrons lost during the formation of the metal ion from its atom

$Y =$ Number of electrons donated by the ligands

$EAN = Z - X + Y$

$36=26-2+Y$

$Y =12$

Hence, the number of monodentate ligand in this complex are $\frac{12}{2}=6$.
