Naming Rings, Alkenes and Alkynes

Alkenes Alkenes: Double bonded carbon Ending: ene Name: Use the same four steps Changes: Carbon 1 is closest to the alkene

Alkenes 1)Find the largest chain that includes the alkene 2)Put in the ene ending instead of ane 3)Number the carbons 1-4 with 1 closest to alkene

Alkenes 1)Find the largest chain that includes the alkene 2)Put in the ene ending instead of ane 3)Number the carbons 1-4 with 1 closest to alkene 1-butene

A Branch and an Alkene 1)Find the longest chain with the alkene butene 2) Count the carbons starting with the closest one to the alkene 1-butene 3) Add in the branch 2-ethyl-1-butene

Alkyne Exactly the same as with alkene

Carbon rings (not aromatics) Same steps: 1)Count the carbons 2)Number the carbons with the functional group as number one 3)Add the word cyclo in front of the name CH 2 – CH 2 l l CH 2 – C – CH 3 l CH 3 1-dimethylcyclobutane
