AI Generated Solution

To determine why cyanoanilinium ion (C₆H₄(CN)⁺NH₃) is a stronger acid than anilinium ion (C₆H₅NH₃⁺), we need to analyze the stability of their conjugate bases. Here’s a step-by-step solution: ### Step 1: Identify the ions - **Cyanoanilinium ion (I)**: C₆H₄(CN)⁺NH₃ - **Anilinium ion (II)**: C₆H₅NH₃⁺ ### Step 2: Determine the conjugate bases - The conjugate base of cyanoanilinium ion (I) is formed by deprotonating the NH₃ group: ...
