Chemistry - GOC Question with Solution | TestHub

Negatively charged bases are far stronger than their neutral counterparts, so NH₂⁻ and OH⁻ beat NH₃ and H₂O. Within each pair, nitrogen is less electronegative than oxygen and holds the electron pair less tightly, making it more available : NH₂⁻ $>$ OH⁻ and NH₃ $>$ H₂O. Hence NH₂⁻ $>$ OH⁻ $>$ NH₃ $>$ H₂O.
