Figuring sum of double bonds and rings ??

Does anyone know how if there is a way to figure out the sum of double bonds and rings of a compound C6H9BrO ?? Lost.. thank you.

This one came up in google :P

Hard to come up with a structural formula from an empirical formula, that's why there are so many chemical analysis methods like NMR/MS.

Double bonds and rings behave differently in spectroscopic analysis, so that would reveal more.

I tried to guess the structure by trial and error heh, knowing some of the bonding rules, but i failed and consulted google, then kicked myself for not remembering the epoxy Oxy type bond.

Maybe there are other structures also, consult a chemical catalogue or database.
