Answer 2

Explanation:

1) pentaamminetricarbonylcobalt(II) Chloride

2) mercury(II) tetrathiocyanatecobaltate(II)

3) diamminechloridonitrito-N-platinum(II)

For Finding Oxidation state :-

1) [Co(NH3)5(CO)3]Cl2

→ x + 0×5 + 0×3 - 1×2 = 0

→ x = 2

2) Hg[Co(SCN)4]

As we know that :-

Hg has +2 charge on it.

So,

[Co(SCN)4] has -2 charge on it

Then,

→ x - 1 × 4 = -2

→ x = 4 - 2

→ x = 2

3) [Pt(NH3)2Cl(NO2)]

→ x + 0×2 - 1 - 1 = 0

→ 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.
