Nomenclature of Organic Compounds Flashcards
What are the three ways in which hydrocarbons can be classified?
Aliphatic
Alicyclics
Aromatic
What is meant by the term aromatic?
Some or all of the carbon atoms are found in a benzene ring.
What is meant by the term alicyclic?
Carbon atoms are joined to each other in ring structures.
What is meant by the term aliphatic?
Carbon atoms are joined to each other in unbranched or branched chains.
What are the three homologous series of aliphatic hydrocarbons that you need to be aware of?
Alkanes
Alkenes
Alkynes
What type of bonds do alkanes have?
Single carbon-to-carbon bonds
What type of bonds do alkenes have?
At least one double carbon-to-carbon bond.
What type of bond do alkynes have?
At least one triple carbon-to-carbon bond.
What does the stem of the name indicate?
The number of carbon atoms in the longest continuous chain.
What can a prefix indicate?
The presence of side chains or functional groups.
What does a suffix indicate?
Functional groups
What is the suffix for alkanes?
-ane
What is meant by the term alkyl group?
These are any side chains that are attached to the parent chain.
What is the name of the alkyl group added to?
The prefix of the name of the parent chain.
What is added before the alkyl group to show where the alkyl group is located?
Numbers
What should you do if there are two or more possible chains of the same length in a molecule?
Use the chain with the most branches as this is considered the longest chain.
What is the order of alkyl groups?
This is done alphabetically.
What prefix should you use when naming alicyclic alkanes?
Cyclo-
What is the suffix for alkenes?
-ene
What must be stated for alkenes that have four or more carbon atoms in their longest chain?
The position of the C=C bond.
