Does Hexatriene have resonance structures?
Does Hexatriene have resonance structures?
Yes, hexatriene has multiple resonance structures.
Do you expect Hexatriene to have multiple resonance structures if not why is this molecule different from benzene with respect to resonance?
Would you expect hexatriene to have multiple resonance structures like benzene? If not, why is this molecule different from benzene with respect to resonance? A. Yes, because double bonds can be moved to give equivalent structures.

Can 1 3 5-Hexatriene be considered an aromatic compound Why do you think so?
1,3,5-Hexatriene has six p orbitals, too, but the two on the terminal carbons cannot overlap with each other, so 1,3,5-hexatriene is not aromatic. Every p orbital overlaps with two neighboring p orbitals. There can be no overlap between the p orbitals on the two terminal C’s.
Why is benzene more stable than Hexatriene?
Because benzene’s pi1 molecular orbital has more stabilizing bonding interactions it is lower in energy than the pi1 molecular orbital of 1,3,5-hexatriene. This gives benzene the additional aromatic stability not seen in the acyclic 1,3,5-hexatriene.
Why are the Kekule structures not adequate to represent the structure of benzene?
In benzene, all of the carbon-carbon bond lengths are equal. Therefore, the Kekule structure shown below is an incorrect representation of benzene. It is incorrect because it suggests that there are two different types of carbon-carbon bonds in benzene, a carbon-carbon double bond and a carbon-carbon single bond.
What are the rules for drawing resonance structures?
Rules for Drawing and Working with Resonance Contributors
- There is ONLY ONE REAL STRUCTURE for each molecule or ion.
- The resonance hybrid is more stable than any individual resonance structures.
- Resonance contributors do not have to be equivalent.
- All resonance contributors must be correct Lewis structures.
What is Huckel rule of aromaticity?
In 1931, German chemist and physicist Erich Hückel proposed a theory to help determine if a planar ring molecule would have aromatic properties. His rule states that if a cyclic, planar molecule has 4n+2 π electrons, it is considered aromatic. This rule would come to be known as Hückel’s Rule.
