Benzimidazole contains a 5-member ring which by itself (lacking the benzene ring) is called "imidazole". Another 5-member ring heterocycle is called "thiophene". Thiophene and imidazole are both aromatic compounds. Please rationalize this claim in a sentence or two, based on your understanding of Huckel's rule and also rationalize by drawing resonance structures showing the stabilization. (Hint: it's easiest to start with thiophene). thiophene imidazole
Electronic Effects
The effect of electrons that are located in the chemical bonds within the atoms of the molecule is termed an electronic effect. The electronic effect is also explained as the effect through which the reactivity of the compound in one portion is controlled by the electron repulsion or attraction producing in another portion of the molecule.
Drawing Resonance Forms
In organic chemistry, resonance may be a mental exercise that illustrates the delocalization of electrons inside molecules within the valence bond theory of octet bonding. It entails creating several Lewis structures that, when combined, reflect the molecule's entire electronic structure. One Lewis diagram cannot explain the bonding (lone pair, double bond, octet) elaborately. A hybrid describes a combination of possible resonance structures that represents the entire delocalization of electrons within the molecule.
Using Molecular Structure To Predict Equilibrium
Equilibrium does not always imply an equal presence of reactants and products. This signifies that the reaction reaches a point when reactant and product quantities remain constant as the rate of forward and backward reaction is the same. Molecular structures of various compounds can help in predicting equilibrium.
![**Aromatic Compounds in Heterocycles: Thiophene and Imidazole**
**Introduction:**
Benzimidazole contains a 5-member ring which by itself (lacking the benzene ring) is called "imidazole." Another 5-member ring heterocycle is called "thiophene." Both of these compounds are characterized by their aromaticity.
**Explanation:**
**Claim:** *Thiophene and imidazole are both aromatic compounds.*
**Analysis:**
Please rationalize this claim in a sentence or two, based on your understanding of Hückel's rule. Additionally, rationalize it by drawing resonance structures that illustrate the stabilization. (Hint: it’s easiest to start with thiophene).
**Diagrams:**
- **Thiophene:** A five-membered ring containing four carbon atoms and one sulfur atom. It is represented with alternating single and double bonds, indicating its aromatic nature.
- **Imidazole:** A five-membered ring containing three carbon atoms, one nitrogen atom, and one nitrogen with an adjacent hydrogen atom. It shows alternating single and double bonds typical of an aromatic system.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fbb0540d8-126b-4df1-bdb3-c8d176e8543c%2F0f7bc9c3-ebd0-4972-acea-bd3f8cca9517%2F647lzep_processed.jpeg&w=3840&q=75)
