Chapter 1 - Nomenclature Flashcards
(14 cards)
Substituents
Functional groups not part of the parent chain
International Union of Pure and Applied Chemistry (IUPAC)
Standards for naming chemical compunds
Alkanes
Hydrocarbons without any double or triple bonds
- CnH(2n+2)
- Named by # of carbons present followed by -ane
Alkenes
Contain double and triple bonds
- named by substituting -ene
Alkynes
Contain double and triple bonds
- Named by substituting -yne
Alcohols
Contain a hydroxyl (-OH) group
- Named by substituting suffix -ol or hydroxy-
Diols
Contain 2 hydroxyl groups
- Geminal if on same carbon
- Vicinal if on adjacent carbon
Carbonyl group
carbon double bonded to an oxygen
Aldehyde
carbonyl group on a terminal carbon that is also attached to a hydrogen atom
- Named with -al or oxo-
Ketones
Carbonyl group on a nonterminal carbon
- Named with -one or oxo- or keto-
Carboxylic Acids
Highest-priority functional group
- Contain 3 bonds to oxygen —> 1 from hydroxyl and 2 from carbonyl
- Always terminal
- Named with -oic acid
Esters
Derivatives where -OH is replaced with -OR, an alkoxy group
- Use -oate or alkoxycarbonyl-
Amides
Replace hydroxyl group of a carboxylic acid with an amino group
- Use -amide, carbamoyl-, or amido-
- Substituents attached to amide nitrogen are designated with N-
Anhydrides
Formed from 2 carboxylic acids by dehydration
- May be symmetric (2 of same acid), asymmetric (2 different acids), or cyclic
- Uses anhydride in place of acid
