Questions & Answers

What is the evidence that disproves the Kekule model for benzene?

The Kekule’s model was disapproved as analytical techniques were used to find its properties and characteristics. The following were the main differences:

  1. Kekule’s structures with three single and three double carbon to carbon bonds suggested a non symmetrical structure with 3 shorter bonds. However, benzene molecule was found to be a palnar, perfectly symmetrical molecule, suggesting all bonds are identical and equal in length.

  2. According to Kekule’s structure, a benzene molecule has three C=C double bonds and should, therefore, undergo electrophilic addition reaction. However, benzene does not undergo electrophilic addition reactions.
