27. higher than alkanes
lower than alcohols: boiling points of 1st and 2nd degree amines?
28. N-H bond weaker than O-H bonds bc N is less electronegative than O: why
are amines lower bp than alcohols?
29. can accept hydrogen bonds but cannot make them intermolecularly: can
tertiary amines have hydrogen bonds?
30. small amines (up to 6 carbons) are soluble: are amines soluble in water? in alcohol?
31. solubility decreases as molecular weight increases: amine aqueous solubility does
what?
32. basic and nucleophilic: are amines acidic or basic?
33. pKb (lower score = more basic): what measures bases
34. alkyl: 3-4, aromatic: 9 (resonance sharing in aromatic): pKb of alkyl amines vs aromatic
amines
35. amine: ammonia + alkyl halide =
36. 1. ammonia as nucleophile displaces halide ion via Sn2 reaction
2.sodium hydroxide (base) added to deprotonate the alkylammonium cation
to produce the "free base" of the amine: 2 steps to alkylation of ammonia and amines
37. alkyl halide added to an ammonia to create an amine: alkylation of ammonia and
amines
38. secondary amine (R2NH): what does a primary amine alkylate to?
39. tertiary amine (R3N): What does a secondary amine alkylate to?
40. quaternary ammonium salt: what does a tertiary amine alkylate to?
41. can produce all degrees of amines: what is advantage of alkylation of amines ?
42. Polyalkylation: yield a mix of amine products because no reaction stops
cleanly after a single alkylation: what is the disadvantage of alkylation of amines?
43. use large concentration of ammonia or amines as the excess helps the
halides not react with the new amines created: how to combat possible polyalkylation?
44. reduced state: all bonds to Nitrogen are either Carbons or Hydrogens
45. Catalytic Hydrogenation: reducing an aromatic nitrogen compound to an aromatic primary amine
on a metal catalyst like nickel or platimum with the addition of high pressured hydrogen gas
