I think in this case it is best to ignore any reaction between bromine (Br2) and water. It is an unnecessary complication. Most HSC Chemistry students will learn that the Br2 molecule simply "adds" onto the alkene, forming a dibromoalkane. Those with a bit more interest in the reaction will discover that the actual product is a mixture of a bromohydrin and a dibromoalkane. The reason for this is because there are hundreds of times more water molecules than bromine molecules in bromine water, which makes it more likely that an OH- (from a water molecule) will add to the alkene than a Br-. I would advise you to stick with 1,2 -dibromocyclohexane rather than 2-bromocyclohexan-1-ol as the product. The whole point of looking at "addition" reactions in the HSC Chemistry course is that the smaller molecule simply adds on to the alkene. For example, water (H2O) + ethene (C2H4) forms ethanol (C2H5OH).
