Naming Esters
Name the alcohol then carboxylic acid
Ethyl Propanoate
Prefix of esters
Oate
Use of Esters
perfumes, solvents and plasticisers
Ester undergoing acid hydrolysis
Forms Carboxylic Acid and Alcohol
Esters undergoing base hydrolysis
Carboxylate Ion and Alcohol
How are Triglycerides formed?
Glycerol and 3 fatty acid chains
Saponification
Fat is hydrolysed with NaOH forms sodium salt and glycerol
How is biodiesel formed?
Oil and methanol with a KOH catalyst reforming glycerol and methyl esters
Prefix of acyl chlorides
-oyl chloride
Ethanoyl Chloride + Water ->
Ethanoic Acid + Hydrogen Chloride
Ethanoyl Chloride + Ammonia ->
Ethanamide + Hydrogen Chloride
Ethanoyl Chloride + Alcohol ->
Methyl Ethanoate + Hydrogen Chloride
Ethanoyl Chloride + Primary Amine ->
N-methyl ethanamide + Hydrogen Chloride
Acid Anhydrides
2 carboxylic acid joined prefix anhydride
Ethanoic Anhydride + Water
2 Ethanoic Acid
Ethanoic Anhydride + Ammonia ->
Ethanamide + Ethanoic Acid
Ethanoic Anhydride + Alcohol ->
Methyl Ethanoate + Ethanoic Acid
Ethanoic Anhydride + Primary Amine ->
N-Methyl Ethanamide + Ethanoic Acid
Nucleophilic Addition Process
Carbon strong + that nucleophiles attack then pair of electron transferred to double bonded oxygen, negative oxygen reforms then Cl bond is broken lone pair of chlorine attacks hydrogen to neutralises positive oxygen
Aspirin
is an ester reacting ethanoic anhydride or ethanoyl chloride
