Flashcards in Solubilities Deck (6):
1

Carboxylic acids

Soluble- due to hydrogen bonds between acid and water molecules

Solubility decreases as hydrocarbon chain length increased and polar effect of carboxyl group I reduced

2

Alcohols

Soluble - hydrogen bond to water molecules

Solubility decreases as chain length increased and the effect of the VDW due to chain length increased

3

Amides

Soluble hydrogen bond to. Water molecules. Solubility decreases as hydrocarbon chain length increased and the polar effect of the amide group decreases

4

Amino acids

Soluble due to ionic properties- strong. Attractions between polar water molecules and zwitterions

5

Amines

Soluble hydrogen bond to water molecules

6

Aldehydes and ketones

Can't hydrogen bond with themselves but can hydrogen bond to water molecules so are soluble- solubility decreases with chain length.....1 of the positive hydrogens in H2O is attracted to the LP on the O of the aldehyde or ketone which forms a hydrogen bond

Also VDW occur between ald or ket and water
