|
|
Term
|
Definition
| Using a reaction called amidation. |
|
|
Term
|
Definition
| When a carboxylic acid reacts with ammonia or a primary or secondary amine. Water is removed and the carboxylic acid and amine molecules join to form an amide. (Like Esters) |
|
|
Term
| What amides can undergo the amidation process? |
|
Definition
Primary and secondary amines, because a hydrogen has to be lost.
CH3-CH2-C-OH + NH2-CH3 -> CH3-CH2-C-NH-CH3 + H2O
|| ||
O O
Propanoic acid + Methylamine-> N-Methylpropanamide + water |
|
|
Term
| What is the IUPAC naming convention for Amides? |
|
Definition
Remove the -ic acid or -oic acid from the carboxylic acid names, then add the suffix amide.
CH3-C-NH2
||
O
Ethanamide |
|
|
Term
| What do you call a benzene ring with an amide group? |
|
Definition
|
|
Term
| What is the relative melting points for amides? |
|
Definition
| High for primary amides, lower for secondary and low for tertiary as there are no hydrogen bonds available to bind with other amdes. |
|
|
Term
| How water soluble are amides? |
|
Definition
| One to five are soluble in water due to hydrogen bondings. |
|
|
Term
| What is hydrolysis of amides? |
|
Definition
The reverse reaction of amide formation (the removal of water). With the addition of water and acid, the amide bond is split creating te carboxylic acid and ammonia/amine.
CH3-C-NH2 + HOH + HCL -> CH3-C-OH + NH4Cl
|| ||
O O
Ethanamide -> Ethanoic acid + ammonium chloride. |
