Consider the weak bases below and their Kb values: C6H7O- Kb = 1.3 × 10-10
C2H5NH2 Kb = 5.6 × 10-4
C5H5N Kb = 1.7 ×10-9
Arrange the conjugate acids of these weak bases in order of increasing acid strength.
A) C5H5NH+< C6H7OH < C2H5NH
B) C6H7OH < C5H5NH+ < C2H5NH
C) C5H5NH+< C2H5NH3+ < C6H7OH
D) C6H7OH < C2H5NH3+< C5H5NH+
E) C2H5NH3+< C5H5NH+ < C6H7OH
