Organic Compound Nomenclature Part 1 Flashcards
meaning of IUPAC
International Union of Pure and
Applied Chemistry
a method of naming organic chemical compounds as recommended by the International Union of Pure and Applied Chemistry (IUPAC). It is published in the Organic Chemistry Nomenclature.
IUPAC Nomenclature of Organic Chemistry
involves a nonsystematic approach to the naming of organic compounds. This nomenclature system is limited to
only a few compounds in each specific group.
trivial nomenclature system
The _____________ indicates the number of carbons in the longest continuous chain.
parent name
The ______ indicates what functional group is present
suffix
The _________ tells us the identity, location, and number of substituents attached to the
carbon chain.
prefix
saturated hydrocarbons in
which the carbon atoms are held
together by single bonds.
named by adding the suffix
-ane to the prefixes.
alkanes
formula of alkanes
CnH2n+2
sequence of prefixes (1-10 carbon atoms)
meth, eth, prop, but, pent, hex, hept, oct, non, dec
If there are two chains of equal length, what would you pick as the parent carbon chain
the chain with more substituents
what do you call the branches attached to the parent chain
substituents
formed by removing one hydrogen from the alkane chain. The removal of this hydrogen
results in a stem change from -ane to -yl
alkyl groups
Number the atoms in the carbon chain to give the first substituent the____________
lower number
Number the atoms in the carbon chain to give the first substituent the____________
lower number
Alphabetize the names of the substituents, ignoring all prefixes
except _____
iso
When numbering a carbon chain results in the same numbers from either end of the chain, assign the lower number ___________ to the first substituent
alphabetically
