####21. According to IUPAC nomenclature sodium nitroprusside is named as

[2003]

(a) Sodium pentacyanonitrosyl ferrate (III)

(b) Sodium nitroferrocyanide

(c) Sodium nitroferrocyanide

(d) Sodium pentacyanonitrosyl ferrate (II)

Show Answer

Solution:

  1. (a) IUPAC name of sodium nitroprusside Na2[Fe(CN)5NO] is sodium pentacyanonitrosoyl ferrate (III) because in it NO is neutral ligand. Hence

2× O.N. of Na+ O.N. of Fe+5× O.N. of CN

1× O.N. of NO=0

2×(+1)+ O.N. of Fe +5×(1)+1×0=0

O.N. of Fe=52=+3, Hence, ferrate (III)
