The correct decreasing order of basic strength of the following species is _______.
H₂O, NH₃, OH⁻, NH₂⁻
Options:
Answer:
A
Solution:
Across the period the anion of the weaker acid is the stronger base: NH₃ (pKa of NH₄⁺ ≈ 38 vs H₂O ≈ 15.7 for its conjugate acid order) gives NH₂⁻ > OH⁻; neutral molecules are weaker than their anions, and NH₃ is a stronger base than H₂O.
