#"Bromine water?"#

Explanation:

An aqueous solution of bromine is commonly added to unknown organic species in order to test for the presence of OLEFINIC bonds....i.e.

#RCH=CHRstackrel(Br_2"/"H_2O)rarrRCH(OH)-CHRBr +HBr#

Of course, the degree of unsaturation may also be expressed as a RING, i.e. cyclohexane has a formula of #C_6H_12#, that is each ring junction reduces the hydrogen count by 2.
