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.
![**Exercise 3: Identifying the Most Acidic Proton(s) and Resonance Structures**
**Instructions:**
1. **Circle the most acidic proton(s):** Identify and encircle the proton(s) in the molecule presented below that demonstrate the highest acidity.
2. **Draw the corresponding conjugate base:** Illustrate the molecule's structure after the most acidic proton(s) has been removed, showcasing the conjugate base.
3. **Draw additional major resonance contributors:** Provide three significant resonance structures for the conjugate base, indicating electron delocalization that stabilizes the ion.
**Diagram Explanation:**
- **Molecule Structure:** The molecule displayed is a five-membered ring, representing a cyclic organic compound with alternating double and single bonds. The presence of two carbonyl groups (C=O) is noted.
- **Indicated Movement:** Arrows indicate possible delocalization of electrons within the conjugate base, which assists in resonance stabilization.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0fcb0af8-b750-4635-b3ee-2f0c31e9ebdb%2Fae38f257-2bbb-495f-8405-1f3df26dfe67%2F2a104mp_processed.jpeg&w=3840&q=75)
