Consider the following isomerism :<br>(i) Ionization (ii) Hydrate (iii) Coordination (iv) Geometrica — Coordination Compounds Chemistry Question

💡 Solution & Explanation

Step 1: Analyze the dissociation of each option in water to determine the number of ions produced per formula unit. Step 2: Option (a) [Pt(NH3)5Cl]Cl3 dissociates into 1 complex cation [Pt(NH3)5Cl]^3+ and 3 chloride ions (Cl^-), totaling exactly 4 ions. Step 3: Option (b) produces 5 ions, option (c) is a neutral molecule producing 0 ions, and option (d) produces 3 ions. Therefore, option (a) is correct.
