✨ Answer with explanation​

Answer 1

Answer:

Sodium nitroprusside dihydrate, 98% | Na2[Fe(CN)5NO] | Sigma-Aldrich

Explanation:

The correct IUPAC name for Na 2

[Fe(CN) 5NO] complex is either

NO in +1 state it is proved by magnetic moment. Name of NO in + 1 state = nitrosonium or nitrosylium

Answer 2

Answer:

Name of the coordination compound = Sodium pentacyanonitrosyl ferrate (III)

Explanation:

Given:

The coordination compound Na₂[Fe(CN)₅ NO]

To Find:

The IUPAC name for the given coordination compound

Solution:

Steps for naming a given coordination compound:

1. Find out whether the given complex is cationic, neutral or anionic

Here the given complex is anionic.

2. Find out the oxidation number of the central metal atom.

The central metal atom given here is Fe.

Oxidation number of Fe = -5 + 2 + x = 0

⇒ -3 + x = 0

⇒ x = 3

Therefore the oxidation number of Fe here is 3.

3. Now while naming the compound, write the name of the non complex part first.

Here the non complex part is sodium.

4. Now write the name of the ligands in alphabetical order.

Here the ligands are cyanide and nitrosyl groups. Since 5 cyanide groups are present the name of the ligands in alphabetical order would be pentacyanonitrosyl.

5. Next write the name of the central metal atom and add the suffix -ate.

Therefore the name of the central metal atom here would be ferrate.

6. Now write the oxidation number in roman numbers.

Here we have already found the oxidation number in step 2 and it is to be written as (III).

Therefore the name of the given coordination compound is Sodium pentacyanonitrosyl ferrate (III)
