Prefix
Indicates the location of the side chains found in the molecule
Parent
Indicates how many carbons compose the molecular backbone ( longest carbon chain).
Suffix
Identifies the family the molecule belongs to, based on the presence and type of functional groups
Isomers
Molecules with the same molecular formula, but different molecule (different structure ). The may differ in physical or chemical properties
Structural isomers
Share molecular formula, but differ in structure ( the order and configuration in which the atoms are bonded to one another).
Stereoisomers
Share molecular structure, but the atomic arrangement differs in space - they cannot be converted into one another by rotation around a single band.
Cis isomer
Type of stereoisomer.
The double bond between carbons is fixed in space ( no free rotation )
Same side group on the same side of the carbons.
Trans isomer
Type of stereoisomer.
The double bond between carbons is fixed in space ( no free rotation )
Same side group on different side of the carbons.
Nitrile
C-N
Suffix: - nitrile
Benzene
Most common and best-known aromatic compound
Colorless
C6H6
Closed ring
Liquid at room temp.
Very stable!!!!!!
Hexane withe 3 double bonds- cyclohex-1,3,5-ene or cyclohex-2,4,6- ene
Arene compounds
Referred as aryl when bonded to a larger molecule.
Contains at least one benzene ring
