In naming a cyclic alkene, the double bond is given positions 1 and 2. The direction of numbering is chosen to give the substituents the lowest possible numbers at the first point of difference.If we start at the carbon with Chlorine as 1 and go towards the Bromine, the double bond is between 1 and 2, and Bromine is at position 3.This gives the set of locants $(1,3)$.Following alphabetical order for naming: 3-bromo-1-chlorocyclohexene.
