Common names of ketones are determined by naming the alkyl or aryl groups attached to the carbonyl group in alphabetical order, followed by the word "ketone." Greek letters, such as alpha (α), beta (β), etc., are used to indicate the position of substituents on the carbon chain. The carbon adjacentRead more
Common names of ketones are determined by naming the alkyl or aryl groups attached to the carbonyl group in alphabetical order, followed by the word “ketone.” Greek letters, such as alpha (α), beta (β), etc., are used to indicate the position of substituents on the carbon chain. The carbon adjacent to the carbonyl group is designated as the alpha carbon, the next as beta, and so forth. Greek letters help specify the location of substituents and provide a systematic way to name ketones with multiple substituents, aiding in the precise identification of their structures in organic chemistry nomenclature.
One historical common name for a ketone is "acetone," derived from the systematic name propanone. Acetone is a simple ketone with three carbon atoms. Its historical common name originates from the fact that it was first discovered and isolated from acetic acid (vinegar). The suffix "-one" indicatesRead more
One historical common name for a ketone is “acetone,” derived from the systematic name propanone. Acetone is a simple ketone with three carbon atoms. Its historical common name originates from the fact that it was first discovered and isolated from acetic acid (vinegar). The suffix “-one” indicates the ketone functional group. Acetone is widely used as a solvent and is familiar as nail polish remover. The historical common name “acetone” reflects its connection to acetic acid and highlights its historical significance in early organic chemistry research and applications.
IUPAC names of aldehydes and ketones are derived from the corresponding alkanes by replacing the "-e" ending of the alkane with "-al" for aldehydes and "-one" for ketones. In aldehydes, the carbonyl group is assigned the lowest possible number, and the suffix "-al" is added to the root alkane name.Read more
IUPAC names of aldehydes and ketones are derived from the corresponding alkanes by replacing the “-e” ending of the alkane with “-al” for aldehydes and “-one” for ketones. In aldehydes, the carbonyl group is assigned the lowest possible number, and the suffix “-al” is added to the root alkane name. For ketones, the carbonyl group is located within the carbon chain, and the suffix “-one” replaces the “-e” ending of the alkane name. Additionally, numerical prefixes (such as di-, tri-, etc.) indicate the position of the carbonyl group if needed. These IUPAC rules provide a systematic and unambiguous way to name aldehydes and ketones.
In the IUPAC naming of cyclic ketones, numbering of carbon atoms is determined to provide the lowest possible locant for the carbonyl group. The carbonyl carbon is assigned the lowest possible number. The specific rule for naming cyclic ketones is to use the prefix "cyclo-" followed by the root alkaRead more
In the IUPAC naming of cyclic ketones, numbering of carbon atoms is determined to provide the lowest possible locant for the carbonyl group. The carbonyl carbon is assigned the lowest possible number. The specific rule for naming cyclic ketones is to use the prefix “cyclo-” followed by the root alkane name for the carbon ring. The carbon atoms are numbered sequentially, starting with the carbonyl carbon as carbon-1. The position of the carbonyl group is then indicated by a numerical locant. This systematic approach ensures clarity and consistency in naming cyclic ketones, helping convey their structural information accurately.
Aromatic aldehydes are named in IUPAC nomenclature by designating the benzene ring as the parent hydrocarbon and adding the suffix "-carbaldehyde" to indicate the presence of the aldehyde group. The position of the aldehyde group is specified by numbering the carbons on the benzene ring. The IUPAC-aRead more
Aromatic aldehydes are named in IUPAC nomenclature by designating the benzene ring as the parent hydrocarbon and adding the suffix “-carbaldehyde” to indicate the presence of the aldehyde group. The position of the aldehyde group is specified by numbering the carbons on the benzene ring. The IUPAC-accepted common name for the simplest aromatic aldehyde is “benzaldehyde.” It is derived from the systematic name “benzenecarbaldehyde,” with the benzene ring as the parent and the carbaldehyde suffix indicating the aldehyde functional group. “Benzaldehyde” is widely used in both IUPAC and common nomenclature for this compound.
