Cyclohexene example in course reader

Postby Eliza_Beglari_2L » Fri Mar 17, 2017 10:23 pm

On page 102 of the course reader, there are more IUPAC naming examples of alkenes. The third example is named 1,6-dichlorocyclohexene. Why is it not 1,2-dichlorocyclohexene?

Because of the double bond. We would have to prioritize the double bond and cross it. You would start with the Chloro right next to the bond as 1 and continue counting from there.

Return to “*Alkenes”
