Question

Write two examples
Complex compound : ?​

Answer 1

Answer:

1. Complex compounds are a large number of molecular compounds which maintain their identities even when dissolved in water or any other solvents.

2. Their physical and chemical properties are completely different from the constituents, these compounds are also called coordination compounds.

3. Examples of the complex compound are:

a) Potassium ferrocyanide K 4 [F e(C N)6 ], and

b) Potassium ferricyanide K 3 [F e(C N)6.

Answer 2

Complex compound:

• A complex ferro cyanide [Fe(CN)6]4- ion is formed when an aqueous solution of Fe(CN)2 and KCN are mixed together.
• The salts of these complexions are known as complex compounds or coordination compounds.
• These complexes usually involve a transition metal and a number of ligands that have lone pairs and might also have the ability to accept electron density back via pi-back-bonding.
• Examples include [Cr(NH3)6](3+)[Cl(1-)]3, H(1+)[AuCl4(1–), {Pt[H2NCH2CH2NH2]2(2+)}[Br(1-)]3, hemoglobin, Vitamin B12, chlorophyll, etc.
