Flashcards in Amines ,amides, amino acids and polymers Deck (10):
1

Making primary amines

Warm haloalkane with excess ammonia, ethanol solvent

2

Polysubstitution of amines...

Amines act as better nucleophiles than ammonia so attack haloalkane to produce secondary and tertiary amines.

3

Making phenylamine

nitrobenzene+6[H] -> phenylamine +2H2O
Sn, conc.HCl, excess NaOH(aq), reflux

4

alpha amino acid

NH2 directly bonded to C atom directly bonded to COOH

5

Enantiomer=

non-superimposable mirror image
50:50 mix=racemic mixture (racemate)

6

Amino acid in acidic conditions

NH3+ group

7

Amino acid in alkaline conditions

COO- group +H2O

8

Making amides

Acyl chloride + NH4 or amine

9

Condensation polymer biproduct number

2n-1

10

Splitting polyamides and polyesters

Hydrolysis under acidic or alkaline conditions
