Problem

Each Lewis structure of benzene has three C=C double bonds. Another hydrocarbon containing three C=C double bonds is hexatriene , C6H8. A Lewis structure of hexatriene is

A six-carbon chain with alternating double and single bond between the carbons; the outer and middle bonds are double bonds.  Each C is single bonded above to H; the terminal Cs are also single bonded below to H.

Experiments show that three of the C-C bonds in hexatriene are shorter than the other two. Does this data suggest that hexatriene exhibits resonance structures?
