1Intermolecular H bonds are not possible or aldehydes and ketones but they are still very soluble in protic solvents.
- AVerdadeiro
- BFalso
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.
- Acarbonyl
- Bnucleophile
- Celectrophile
- Dacid
- Ebase
- Fwithrdawing
- Gdonating
3A lactam is a cyclic amide.
- AVerdadeiro
- BFalso
4Amides can hydrogen bond with other amides.
- AVerdadeiro
- BFalso
5Amides are chemically stable because:
- AThey are resonance stabilized.
- BThey have no reactive lone pair of electrons.
- CThe oxygen is very electron withdrawing.
6Lactones and carbamates are classified as esters.
- AVerdadeiro
- BFalso
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.
- Apolar
- Bnon-polar
- Ccannot
- Dcan
- Every soluble
- Fvery insoluble
8Phosphate esters make drugs very soluble, which is useful for formulating drugs meant to be injected intravenously.
- AVerdadeiro
- BFalso
