Problems and exercisesAmines, anilines and other nitrogen functions

1. Primary, secondary, tertiary or quaternary

Classify each nitrogen compound:

1. CH₃CH₂NH₂
2. (CH₃CH₂)₂NH
3. (CH₃)₃N
4. (CH₃)₄N⁺ Cl⁻
5. Piperidine
6. C₆H₅NH₂

2. Base and nucleophile

Which structural feature explains why amines are both bases and nucleophiles? Give an example of each behaviour.

3. Nitrogen families

Give the oxidation state of nitrogen in: CH₃NH₂, CH₃N=C=O, CH₃N₃ (the atom bonded to carbon) and CH₃NO₂.
