Question

Which of the following statement(s) is (are) correct?

Options

A.The oxidation state of iron in sodium nitroprusside Na2[Fe(CN)5(NO)] is +2.
B.[Ag(NH3)2]+ is linear in shape.
C.In [Fe(H2O)6]3+, Fe is d2sp3 hybridized.
D.In Ni(CO)4, the oxidation state of Ni is zero.

Solution

Sol. (A) The NO in sodium nitroprusside in +1 oxidation state so :

Na2[Fe(CN)5(NO)] ⇒ 2Na+ + [Fe(CN)5(NO)]–2

So oxidation state of Fe :

x + (–5) + 1 = –2

x – 4 = –2 ⇒ x = +2

(B) [Ag(NH3)2]+

[NH3: → Ag ← :NH3]+

Linear

sp2-hybridization

(D) CO is neutral ligand so oxidation of Ni in [Ni(CO)4] is zero.
