The magnesium likes  the bromine. So what will be left if magnesiumbromide is gone?

Only cyclo hexane or?

No, do you know the Wurtz reaction. Where did you left the benzyl group.

I'm not sure. Is it (Cyclohexylmethyl)benzene?

Are you familiar with the term "grignard reagent"? The molecule on the left side of the arrow is one (simplified with: RMgX (R=carbonchain, X=halogene)).

The Br molecule which is attached to toluene (simplified as RX) reacts as a leaving group when RMgX attacks it.

I think chenbeier made it all clear to you yesterday. But  maybe this makes it more clear.

Also a tip: If you get a question where bromocyclohexane reacts with Mg (as the reagent) it will also form the molecule on the left side of the arrow.
