Question
'All Lewis bases are also Bronsted bases'. Is it true? If yes, Why?
✓
Answer
Yes, it is true. It is because Lewis bases are- vely charged or electron rich. They are Bronsted bases also because they can accept $\mathrm{H}^{+}$easily, e.g., $\mathrm{NH}_3$ can donate electron (Lewis base) and accept $\mathrm{H}^{+}$ (Bronsted base).
