Identify the strongest base according to Bronsted-Lowry theory from following.

Options

  1. ACl ^-
  2. BCH ₃ COO ^-
  3. CNO ₃^-
  4. DHSO ₄^-

Correct answer

B. CH ₃ COO ^-

Step-by-step solution

According to the Bronsted-Lowry theory, a stronger base has a weaker conjugate acid. The conjugate acids of the given bases are: Cl ^- HCl (strong acid) CH ₃ COO ^- CH ₃ COOH (weak acid) NO ₃^- HNO ₃ (strong acid) HSO ₄^- H ₂ SO ₄ (strong acid) Since CH ₃ COOH is the weakest acid among the given conjugate acids, its conjugate base CH ₃ COO ^- is the strongest base. Answer: CH ₃ COO ^-
