Question

Which of the following is a property of coordination compound and not of double salt?

• A. These dissociate into their constituent ions when dissolved in water.
• B. These show entirely different properties from their constituent ions.
• C. These lose their identity in aqueous solution.
• D. Aqueous solution of these gives the tests of all constituent ions.

Hint:

Coordination compounds exhibit properties that are different from their constituent ions due to the presence of coordination bonds between the metal and the ligands.

Answer 1

The Correct Option is B

Step 1: Understanding the properties.
Coordination compounds are complex compounds that consist of a central metal atom bonded to ligands. These compounds exhibit distinct properties from their constituent ions, which is a defining feature of coordination compounds.
Step 2: Analyzing the options.
(A) These dissociate into their constituent ions when dissolved in water: This is true for salts, but not specific to coordination compounds.
(B) These show entirely different properties from their constituent ions: Correct. Coordination compounds have distinct properties from the individual ions they contain due to the metal-ligand bonds.
(C) These lose their identity in aqueous solution: Incorrect. Coordination compounds retain their identity in solution.
(D) Aqueous solution of these gives the tests of all constituent ions: Incorrect. Coordination compounds do not necessarily show tests for all their constituent ions.
Step 3: Conclusion.
The correct answer is (B) These show entirely different properties from their constituent ions.
