Is the answer 3 or 4?

i checked my destroyer. says 3

I would say 3. Are you thinking 4 because you want to add Br in between the two rings where there's a 3° carbon?

3, it cannot add to the carbon that connects the 2 rings because that carbon doesn't have a hydrogen on it

I just noticed something. It says napthalene, but isn't that anthracene? Napthalene is only 2 rings..

Yes that was what I was about to say =)
