Alkylation of enolates can be difficult to control.. The alkylation of an aldehyde or ketone enolate is an example of a nucleophilic substitution reaction.. The alkylation of aldehydes and ketones is complicated by several unwanted side reactions.. In General. Fragrant odors. Basic building block of housing materials. Hormones. Digestion. Vision. 2. In General. Carbonyl group. C=O. Aldehydes. RCH=O. Formyl. Ketones. RC=OR’. 3. Nomenclature. Chemistry of Cooking. Flavours in Food. Many of the flavours in foods are due to the presence of . volatile. molecules. . Many . flavour and aroma molecules belong to the family called . aldehydes. . 17-1. The aldehyde function takes precedence over the ketone group in nomenclature.. Simpler aldehydes often retain their common names. These are constructed by dropping the –. ic. or –. oic. . 18-1. The pK. a. values of the . -hydrogens of aldehydes and ketones range from 16 to 21, comparable to those of alcohols (15-18).. Strong bases can remove  hydrogens leading to anions called .

Many organic compounds contain an atom or group of atoms that substitute for hydrogen or carbon in a basic hydrocarbon.. The atom or group of atoms is commonly referred to as functional group.. Carbonyl Compounds. Contain the carbonyl group . C=O. . Aldehydes: . R may be hydrogen, usually a carbon containing group. Ketones: . R contains carbon. Short. forms.
