Can a Reaction Occur Between Cyclohexane and Bromine Water?

[danago]

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 occurred, and so an equation cannot be written? Would i write a partial substitution reaction equation?

Thanks for the help,
Dan.

You're right, no reaction should occur between these two molecules. I suppose if I had to write a reaction, I would just write cyclohexane + bromine --> cyclohexane + bromine. I think it would probably be clearer though to simply state that no reaction occurs.
