Amines (OCR A-Level Chemistry A): Flashcards

$\text{NH}_3$ with H replaced by C chains/rings

Primary (1), secondary (2), tertiary (3)

$\text{RNH}_2$

Lone pair on N accepts $\text{H}^+$

Dative covalent bond

Salt (ammonium salt)

Nucleophilic substitution: haloalkane + $\text{NH}_3$

Ethanol (prevents alcohol formation)

Reduces further substitution to 2°/3° amines

Reduction: Sn/conc HCl (reflux), then NaOH
