Carboxylic Acids Flashcards
1
Q
Give 4 ways to prepare carboxylic acids.
A
Oxidation of primary alcohols
Hydrolysis of esters
Hydrolysis of amides
Hydrolysis of nitriles
2
Q
Give 4 examples of reactions of carboxylic acids.
A
React with alcohols to form esters
React with metals and bases to form salts
React with amines to form amides
Reduction to form primary alcohols
3
Q
Describe the m.pt/b.pt of carboxylic acids.
A
Carboxyl group is polar - hydrogen bonding between molecules means elevated melting and boiling points compared to non-polar molecules of similar mass
4
Q
Describe the solubility of carboxylic acids.
A
Short chain acids are soluble in water - from H-bonds with water molecules
The longer the carbon chain, the less soluble it is
