6. Shape and bond angle of amines
- trigonal planar, 120
- pyramidal, 107.5
- tetrahedral, 107.5
- pyramidal, 109.5
7. larger amines (>5 Carbons) are not soluble in water due to
- increased chain length- vdw forces too weak to separate h20 molecules
- decreased chain length- more vdw forces present
- size- too big to be dissolved
- carbons repel the water molecules
8. amines react with acids to form
- acid anhydride
- salts
- amides
- carbonyl compound
9. tertiary amines have boiling points similar to those of
- carbonyls
- hydrocarbons
- alkyls
10. why do amines have lower boiling points than alcohols?
- N-H bond less polar than O-H bond
- functional group is hydrophobic
- N-H bond more polar than O-H bond
- due to their size
