Explain the following observations: (a) HCl is a stronger

Problem 16.88 Explain the following observations: (a) HCl is a stronger acid than H S; (b) H PO is a stronger 2 3 4acid than H AsO ; (c) HBrO is a stronger acid than HBrO ; (d) H C O is a stronger acid than 3 4 3 2 2 2 4HC O -; (e) benzoic acid (C H COOH) is a stronger acid than phenol (C H OH). 2 4 6 5 6 5 Step-by-step solution Step 1 of 5 (A) HCl is a stronger acid than H S, as in the case o2binary acid as we move along the period from left to right electronegativity of element X increases hence H-X bond becomes more polar and acid strength increases.
