How do you identify the parent chain?
The longest chain of carbons containing the highest priority functional group
How do you number the chain?
Ensure the highest priority group has the lowest number
If multiple similar groups, ensure lowest possible numbers for all substituents
You cannot number into or out of a ring
What are the prefixes for naming the parent chain 1-12?
How do you determine parent chain priority?
Alkenes > Alkynes > Alkanes
What is this substituent?
Isopropyl
What is this substiuent?
Sec-butyl
What is this substituent?
T-butyl
What is this substituent?
Isobutyl
How do you name substituents of the same type?
How do you name substituents attached to the parent chain?
Alkane = -yl
Alkene = -enyl
Alkane = -ynyl
What are enatiomers?
All stereocenters switched between 2 structures. Only difference in compounds are optical rotation
What are diastereomers?
Must have 2 stereocenters and one stereocenter must remain the same.
They have completely different properties.
What other way can you name disubstituted benzenes with common names without numbers?
- Ortho - 1,2
- Meta - 1,3
- Para - 1,4
