Question

Pick the stronger base from each pair. a. ClO₄^– or ClO₂^– b. Cl^– or H₂O c. CN^– or ClO^–

Accepted Answer

Step 1: Understand the concept of base strength. A stronger base is more willing to accept protons (H+ ions) or donate electron pairs. The strength of a base is often related to the stability of its conjugate acid.. Step 2: Analyze the conjugate acids of each pair. For example, the conjugate acid of ClO4– is HClO4, and the conjugate acid of ClO2– is HClO2. Compare the acid strengths to determine the base strengths.. Step 3: Use the concept of acid strength to infer base strength. A weaker acid has a stronger conjugate base. For instance, if HClO4 is a stronger acid than HClO2, then ClO2– is a stronger base than ClO4–.. Step 4: Consider the electronegativity and size of atoms involved. For example, Cl– is the conjugate base of HCl, a strong acid, making Cl– a very weak base. Compare this with H2O, which is a weak acid, making it a relatively stronger base than Cl–.. Step 5: Evaluate the stability of the base. For CN– and ClO–, consider the resonance and electronegativity. CN– has resonance stabilization and is a stronger base compared to ClO–, which has less resonance stabilization.
