Question

[CoCl2(NH3)4]+ IUPAC name

Answer 1

Explanation:

tetraammidedichlorido cobalt(III)

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.
• O.N. is written in Roman number.

Here, Ligan number is 2 and 4

Ligan name is Chlorido (Cl) and ammide (NH3).

Metal name is Cobalt.

O.N. is 3 (III).

Calculation of O.N. :-

→ x - 1 × 2 + 0 × 4 = 1

→ x = 1 + 2

→ x = 3
