    Study Notes

    Carboxylic Acids

    • Carboxylic acids are formed by the oxidation of aldehydes.

    Aldehydes and Ketones

    • Aldehydes and ketones have a carbonyl functional group in common.
    • In aldehydes and ketones, the carbonyl carbon is bonded to a carbon atom and a hydrogen or an alkyl group respectively.

    Carboxyl Functional Group

    • The carboxyl functional group is characterized by the carbonyl carbon being bonded to an oxygen and an -OH group.

    Phenol Acidity

    • Phenol is more acidic than aliphatic alcohols due to the resonance stabilization of the phenoxide ion.

    Ethers

    • A characteristic feature of ethers is that they are neutral compounds and do not react with NaOH.

    Alcohols Preparation

    • A common method for the preparation of alcohols is the hydration of alkenes in the presence of an acid catalyst.
