Question

name of K4[Fe(CN)6]
​

Answer 1

Explanation:

Potassium hexacyanidoferrate(II)

Calculation of O.N. -

Let x be the O.N. of Fe

Then,

→ x - 1×6 = -4

→ x = 6 - 4

→ x = +2

Additional information -

In inorganic chemistry IUPAC name is written by following steps :-

For Cationic complex -

• Ligan number + Ligan name + metal name (in English) + O.N. (oxidation number)

For Anionic complex -

• Ligan number + Ligan name + metal name(Latin) + -ate + O.N.

For Neutral complex -

• Ligan number + Ligan name + metal name (in English) + O.N. (same as cationic complex)

Sum of oxidation number of all the atoms of a molecule is zero.
