Question

What is iupac name for [zn(ncs)4]2-

Answer 1

Explanation:

Tetraisothiocyanatozincate(II)

Explaination :-

As we see that it is an Anionic complex. So, we write its IUPAC Name by the rule of Anionic complex.

Here,

Ligan number = 4 (tetra)

Ligan name = thiocyanato (NCS)

metal name + -ate = zincate

O.N. = +2

Calculation of O.N. :-

→ x - 1 × 4 = -2

→ x = 4 - 2

→ 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.
