Q: Which of the following compounds is a coordination complex?

Solution: Ag(NH3)2Cl is a coordination complex where silver is coordinated to two ammonia molecules.

Steps: 5

Step 1: Understand what a coordination complex is. A coordination complex consists of a central metal atom or ion bonded to surrounding molecules or ions called ligands.
Step 2: Identify the central metal in the given compound Ag(NH3)2Cl. Here, silver (Ag) is the central metal.
Step 3: Look for ligands in the compound. In Ag(NH3)2Cl, there are two ammonia (NH3) molecules acting as ligands.
Step 4: Check if there are any other ions or molecules attached to the central metal. In this case, there is also a chloride ion (Cl) present.
Step 5: Conclude that since silver is bonded to two ammonia molecules and one chloride ion, Ag(NH3)2Cl is indeed a coordination complex.
