Why it matters

This objective helps connect Amines (A-level only) to exam-style questions, flashcards, and revision notes for Amines (A-level only).

Quick student answer

Which of the following statements best explains the basicity of amines?

Direct answer

The lone pair of electrons on the nitrogen atom can accept a proton.

Key terms

  • Basicity: The ability of a substance to accept protons (H+) or donate electron pairs.
  • Lone pair: A pair of valence electrons that are not shared with another atom and can be used to form bonds.

Common trap

Confusing basicity with acidity: Remember that basicity refers to the ability to accept protons, while acidity refers to the ability to donate protons.
