@AriHoresh

hey, what is the correct answer? is it A?

Hey, correct answer is D

Hi! So I think when there are halogens involved, I usually draw them out so if anyone has a less time consuming method please let me know! I included the optical isomers as well which applies to some of the compounds.

Usually if it’s just a hydrocarbon I would use the equation 2^(n-4)+1

Hope it helps!
