Study Notes

Aldehydes and Ketones: Nucleophilic Addition Reactions

Aldehydes and ketones are characterized by the carbonyl functional group and are the most abundant compounds in nature.
Carbonyl compounds have many industrial applications, including solvents, polymers, and flavorings.
The carbonyl group consists of a double bond between carbon and oxygen, with carbon being electrophilic and oxygen being nucleophilic.
Carbonyl compounds can be categorized into two general groups: aldehydes and ketones, and carboxylic acids and their derivatives.
Aldehydes are named by selecting the parent carbon chain containing the -CHO group and replacing the terminal -e of the corresponding alkane with -al.
Ketones are named by selecting the parent carbon chain containing the -C=O group and replacing the terminal -e of the corresponding alkane with -one.
Aldehydes and ketones can also serve as substituents and are named using the suffix -yl or the prefix oxo-.
Aldehydes can be synthesized by oxidizing primary alcohols, while ketones can be synthesized by oxidizing secondary alcohols or hydrating terminal alkynes.
Tollens' reagent can be used to identify the presence of an aldehyde group in a molecule.
Aldehydes and ketones undergo nucleophilic addition reactions, including reduction with NaBH4 or LiAlH4 to produce alcohols.
Nucleophiles can be negatively charged or neutral and can include water, alcohols, amines, and Grignard reagents.
Nucleophilic addition of water to aldehydes or ketones yields 1,1-diols, while addition of alcohols produces acetals. Acetals can serve as protecting groups for aldehydes and ketones.
