Write and draw

Answer 1

RCONR
Check drawing on oneNote

Question 2

Amides properties

Answer 2

• Solids
• Aliphatic amides are soluble in water as they contain 2 electronegative atoms and polar bonds so can form hydrogen bonds
• the carbon is very electron-deficient as it joins to nitrogen and oxygen

Question 3

Equation for the formation of amides
Visible product

Answer 3

RCOCl + NH3 —> RCONH2 + HCl
Misty fumes of HCl

Question 4

Reaction between products of the formation of amides
And why this happens

Answer 4

NH3 + HCl —> NH4Cl
Ammonia is basic and HCl is acidic

Question 5

Conditions and process of reaction

Answer 5

Acyl chloride in concentrated aqueous ammonia

Lone-pair of electrons on the nitrogen are strongly attracted to the carbon of the acyl chloride.
The acyl chloride combines with one of the hydrogen atoms to form hydrogen chloride in misty fumes

Question 6

What are polyamides formed from

Answer 6

The monomers, dicarboxylic acid and diamond

Question 7

Describe the movement of atoms during formation of polyamides

Answer 7

The carboxylic acid has an acid group and the amine is basic so they react to form a CONH with the elimination of water - condensation

Question 8

Question 10

Describe and draw Kevlar

Answer 10

If benzene rings take place of the CH2 groups than Kevlar is produced.
It is used mostly in bullet-proof vests.
