This question already has an answer here:

I saw this cyclohexene in my textbook and wonder why it’s like that. I searched the internet and it’s correct but why?
As I know we try to keep the numbers low, so instead of 1,6-dichlorocyclohexene we can tell 2,3-dichlorocyclohexene and the numbers are lower. I appreciate your help.

1,6-dichlorocyclohex-1-ene
