Aliphatic amines (reactions using ethylamine) Flashcards
1
Q
Smell?
A
Fish-like
2
Q
Shape of bond?
A
107 degrees
3
Q
Why are they bases?
A
due to the lone pair of electrons on the nitrogen, amines are proton acceptors

ethylammonium ion and OH- ion
7
Q
Reaction with an acid?
A
ethylammonium chloride (with HCl)
8
