C6H6, a flat symmetrical molecule with a 
structural formula that is often formalized as 
that of cyclohexatriene- in other words, as a 
structural formula that involves a six-
membered carbon ring which 3 double bonds 
are present.
(Benzene itself is implicated as  cancer 
causing chemical)

This structure is one of two equivalent structures that can be 
drawn for benzene that differ only in the locations of the 
double bonds(1,3,5, positions versus 2,4,6 positions):
Neither of these conventional structure, however is totally 
correct.

Experimental evidence indicates that all 
of the carbon-carbon bonds in benzene 
are equivalent (identical), and these 
structure imply three bonds of one type 
(double bonds) and three bonds of a 
different type (single bonds)
