Predict the direction of the following equilibrium and the approximate value of Keq.
ArOH + RNH₂ ArO⁻ + RNH₃⁺ (pKa ≈ 10 and ≈ 10)
Options:
Answer:
C
Solution:
The acid on the left is the phenol (pKa ≈ 10) and the acid on the right is the alkylammonium ion (pKa ≈ 10). The two acids are equally strong, so neither side is favoured and Keq ≈ 10¹⁰⁻¹⁰ = 1.
