Table of Functional Group Priorities for Nomenclature
2011年2月14日 · If you have a molecule with, say, a carboxylic acid and a ketone you consult the table. he functional group with the highest priority will be the one which gives its suffix to the name of the molecule. So in example #1 above, the suffix of the molecule will be “-oic acid” , not “-one”, because carboxylic acids are given higher priority.
Nomenclature of Aldehydes & Ketones - Chemistry LibreTexts
Ketones contain the carbonyl group bonded to two carbon atoms. Aldehydes and ketones are organic compounds which incorporate a carbonyl functional group, C=O. The carbon atom of this group has two remaining bonds that may be occupied by hydrogen, alkyl or aryl substituents.

The one ending shows that it is a ketone, and so has a C=O group somewhere in the middle. Attached to the carbon chain is a phenyl group. Putting that together gives: phenyl ethanoate. This is an ester based on ethanoic acid. The hydrogen atom in the -COOH group has been replaced by a phenyl group.

1.2: Aldehydes and Ketones- Structure and Names
2021年5月22日 · In a ketone, two carbon groups are attached to the carbonyl carbon atom. The following general formulas, in which R represents an alkyl group and Ar stands for an aryl group, represent ketones. In an aldehyde, at least one of the attached groups must be a hydrogen atom.
Topics in Organic Chemistry: Ketones : Structure and Nomenclature
2021年4月2日 · Ketones are the organic compounds with carbon –oxygen double bond (C=O; carbonyl group). They have general formula (RCOR). Key words: Ketone, Carbonyl compound, Common names and IUPAC nomenclature of ketones. Introduction. The ketones have general formula as R-C(O)-R ; where R can be alkyl or aromatic.
One of the most common reaction themes of a carbonyl group is addition of a nucleophile to form a tetrahedral carbonyl addition compound (intermediate). Problem: 2-phenyl-2-butanol can be synthesized by three different combinations of a Grignard reagent and a ketone. Show each combination. Note: Water can also be added to ketones & aldehydes.
