Amines + Amino acids

Question 1

What is reaction between methylamine and HCl

Answer 1

It makes methylammonium (CH3NH4) + Cl-

Question 2

What is the reaction between ethylamine and H2SO4

Answer 2

It forms di ethylammonium salts C(CH3CH2NNH3+)2 SO4

Question 3

How to produce primary amines

Answer 3

Reacting haloalkane with excess ammonia -> 2NH3 + C2H5Br -> NH4Br + C2H5NH2

Question 4

How to produce secondary amines

Answer 4

Reacting haloalkane with primary amines -> C2H5NH2 + C2H5Br -> (C2H5)2 Nh + HBr

Question 5

How to tertiary amines

Answer 5

Reacting haloalkane with secondary amines -> (C2H5)3N + HBR

Question 6

How do you make a polyester

Answer 6

-OH from carboxyl group reacting with -OH from alcohol group

Question 7

How do you make a polyamide

Answer 7

-OH from carboxyl group reacting with -NH from amine group

Question 8

What reactants do you use to hydrolyse polyesters and polyamides

Answer 8

H20 for polyamides and NaOH for polyesters

Question 9

How are esters formed from amino acids

Answer 9

Alcohols + Amino Acids

Question 10

Why are polyesters biodegradable

Answer 10

The ester bond can be hydrolysed in water

Question 11

How to go from -NO2 to -NH2

Answer 11

We need Sn and HCl and and 6 [H] and this also produces 2 H2O

Question 12

What is the reaction between amino acid and HCl

Answer 12

In amino acid: -NH2 becomes -NH3 and it is a.a _ Cl-

Question 13

What is meant by optical isomer

Answer 13

Non super imposable mirror images
