Hey. In class, we did an experiment where we tested the reactivity of alkanes, alkenes and aromatics. One of the tests was a reaction between cyclohexane and bromine water. When we mixed them, nothing noticeable happened. The bromine water stayed a reddish brown colour. I now have to write an equation for this reaction. My question is, in a situation like this, do i assume no reaction at all occured, and so an equation cannot be written? Would i write a partial substitution reaction equation? Thanks for the help, Dan.
