what are the two objections in kekule's formula of benzene???
Answers
Answer:
Kekule's structure does not explain the extra ordinary stable nature of benzene molecule and its lack of reactivity towards addition reactions, resistance towards oxidation etc. (iii) Equivalence of all the carbon-carbon bond lengths in benzene.
Answer:
The extraordinary stability of the benzene molecule, as well as its resistance to oxidation and lack of reactivity to addition reactions, are not explained by Kekule's structure.
Explanation:
The structure of Kekule has the following drawbacks:
1. According to the Kekule structure, the two unique bonds in the benzene structure should be represented by two different 1,2-bromobenzenes.
2. However, only one 1,2-bromobenzene has ever been found, proving that all benzene bonds are equivalent and form resonance with one another.
3. According to Kekule's structure, benzene has three double bonds, thus its chemical characteristics ought to be comparable to those of an alkene. In reality, though, this is not true because benzene is incredibly stable and easily transforms into replacement molecules.
4. The Kekule structure predicts that there will be two different kinds of bond lengths in the structure.
Hence, above are the objections to Kekule's formula of benzene.
