They have no reactive lone pair of electrons.

The oxygen is very electron withdrawing.

1Intermolecular H bonds are not possible or aldehydes and ketones but they are still very soluble in protic solvents.
1. ARichtig
2. BFalsch
2Aldehydes and ketones can form hydrates (two -OH groups off one carbon that was a [blank_start]carbonyl[blank_end] carbon). The oxygen in water acts as the [blank_start]nucleophile[blank_end]. This occurs in an [blank_start]acid[blank_end] catalysed reaction. The more electron [blank_start]withrdawing[blank_end] the substituents of the carbonyl carbon are, the more hydrate is formed.
1. Acarbonyl
2. Bnucleophile
3. Celectrophile
4. Dacid
5. Ebase
6. Fwithrdawing
7. Gdonating
3A lactam is a cyclic amide.
1. ARichtig
2. BFalsch
4Amides can hydrogen bond with other amides.
1. ARichtig
2. BFalsch
5Amides are chemically stable because:
1. AThey are resonance stabilized.
2. BThey have no reactive lone pair of electrons.
3. CThe oxygen is very electron withdrawing.
6Lactones and carbamates are classified as esters.
1. ARichtig
2. BFalsch
7Esters are [blank_start]polar[blank_end], and [blank_start]cannot[blank_end] form intermolecular H bonds. They are however still [blank_start]very soluble[blank_end] in protic solvents due to their H bonding.
1. Apolar
2. Bnon-polar
3. Ccannot
4. Dcan
5. Every soluble
6. Fvery insoluble
8Phosphate esters make drugs very soluble, which is useful for formulating drugs meant to be injected intravenously.
1. ARichtig
2. BFalsch
