The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

The correct answer is: B) ClO\u207b<\/strong><\/p>\n\n\n\n

\n\n\n\n

Explanation:<\/h3>\n\n\n\n

To determine the strongest conjugate base<\/strong>, we need to understand the inverse relationship between the strength of an acid and the strength of its conjugate base<\/strong>:<\/p>\n\n\n\n

    \n
  • A weaker acid<\/strong> (lower Ka) has a stronger conjugate base<\/strong>.<\/li>\n\n\n\n
  • A stronger acid<\/strong> (higher Ka) has a weaker conjugate base<\/strong>.<\/li>\n<\/ul>\n\n\n\n

    Let\u2019s list the acids with their Ka values in ascending order (from weakest acid to strongest):<\/p>\n\n\n\n

    Acid<\/th>Ka<\/th>Conjugate Base<\/th><\/tr><\/thead>
    HClO<\/td>3.0 \u00d7 10\u207b\u2078<\/td>ClO\u207b<\/strong><\/td><\/tr>
    HOAc (acetic acid)<\/td>1.8 \u00d7 10\u207b\u2075<\/td>OAc\u207b<\/strong><\/td><\/tr>
    HCHO\u2082 (formic acid)<\/td>1.8 \u00d7 10\u207b\u2074<\/td>CHO\u2082\u207b<\/strong><\/td><\/tr>
    HF<\/td>6.8 \u00d7 10\u207b\u2074<\/td>F\u207b<\/strong><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

    From this, we can see that HClO is the weakest acid<\/strong> because it has the smallest Ka. Therefore, its conjugate base, ClO\u207b<\/strong>, must be the strongest base<\/strong> among the choices.<\/p>\n\n\n\n

    Now let’s consider each choice:<\/p>\n\n\n\n

      \n
    • A) OAc\u207b<\/strong>: Comes from HOAc, a stronger acid than HClO. Not the strongest base.<\/li>\n\n\n\n
    • B) ClO\u207b<\/strong>: Comes from HClO, the weakest acid. Strongest base<\/strong>.<\/li>\n\n\n\n
    • C) CHO\u2082\u207b<\/strong>: Comes from HCHO\u2082, stronger acid than HOAc and HClO.<\/li>\n\n\n\n
    • D) F\u207b<\/strong>: Comes from HF, the strongest acid here, so its conjugate base is the weakest.<\/li>\n\n\n\n
    • E) OAc\u207b and CHO\u2082\u207b<\/strong>: Both are weaker bases than ClO\u207b, so this is incorrect.<\/li>\n<\/ul>\n\n\n\n

      Conclusion:<\/h3>\n\n\n\n

      Because ClO\u207b is the conjugate base of the weakest acid (HClO)<\/strong>, it is the strongest base<\/strong> listed. Thus, option B is correct<\/strong>.<\/p>\n\n\n\n
