21.11 Aryl Halide and Nucleophilic Aromatic Substitution 21.12 Spectroscopic Analysis of Phenols and Aryl Halides

The aldols formed in aldol additions can be easily dehydrated to yield conjugated enals (enones)

Acetylenic hydrogens can be deprotonated with relatively strong bases (sodium amide is typical)

One complication associated with alkene hydration is the occurrence of arrangements

Alkenes are hydrocarbons whose molecules contain the carbon-carbon double bond. Alkynes are hydrocarbons whose molecules contain the carbon-carbon triple bond

The most characteristic reaction of aldehydes and ketones is nucleophilic addition to the carbon-oxygen double bond

Alcohols are compounds whose molecules have a hydroxyl group attached to a saturated carbon atom
