Amines ,amides, amino acids and polymers Flashcards
1
Q
Making primary amines
A
Warm haloalkane with excess ammonia, ethanol solvent
2
Q
Polysubstitution of amines…
A
Amines act as better nucleophiles than ammonia so attack haloalkane to produce secondary and tertiary amines.
3
Q
Making phenylamine
A
nitrobenzene+6[H] -> phenylamine +2H2O
Sn, conc.HCl, excess NaOH(aq), reflux
4
Q
alpha amino acid
A
NH2 directly bonded to C atom directly bonded to COOH
5
Q
Enantiomer=
A
non-superimposable mirror image
50:50 mix=racemic mixture (racemate)
6
Q
Amino acid in acidic conditions
A
NH3+ group
7
Q
Amino acid in alkaline conditions
A
COO- group +H2O
8
Q
Making amides
A
Acyl chloride + NH3 or amine
9
Q
Condensation polymer biproduct number
A
2n-1
10
Q
Splitting polyamides and polyesters
A
Hydrolysis under acidic or alkaline conditions
