Amines Flashcards
1
Q
How are amines prepared from akylhalides?
A
Primary amines are prepared by reacting akylhalides and ammonia in the presence of water and base. (Aminolysis)
2
Q
What are the physical properties of amines?
A
- Amines have a choking sell.
- Amines are polar compounds and have intermolecular hydrogen bonding with the exception of tertiary amines. Hence, lower amines are soluble in water.
3
Q
What is the functional group of amines?
A
NH2
4
Q
How are amines prepared from nitroalkanes?
A
Amines are prepared from nitroalkanes in the presence of Tin, HCl, and heat.
5
Q
How are amines prepared from nitrides?
A
Amines are prepared from the reduction of nitrides by the reducing agent LiAlH4.
6
Q
How are amines prepared?
A
- Substitution reaction between alkylhalides and ammonia in the presence of water and a base (NaOH).
- Reduction of nitroalkanes in the presence of heat, tin, and HCl.
- Reduction of alkane nitrides in the presence of LiAlH4
