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.

Question

**Ranking Cycloalkenes by Stability**

In the diagram above, four cycloalkenes are shown, labeled A, B, C, and D. The task is to rank these compounds in order of increasing stability (from least stable to most stable).

- **Compound A** is a cyclohexene with an alkyl substituent.
- **Compound B** is a cyclopentene with a similar substituent.
- **Compound C** is a cyclohexene without any additional substituents.
- **Compound D** is a cyclopentene with an alkyl substituent directly attached to the double bond.

### Key Considerations:

1. **Substituents on Alkenes:** Alkyl substituents can stabilize alkenes via hyperconjugation and the inductive effect.
2. **Ring Size and Double Bond:** Larger rings like cyclohexene are generally more stable due to less angle strain compared to smaller rings like cyclopentene.
3. **Position of the Double Bond:** The stability of the double bond in relation to the ring and substituents can influence overall stability.

In general, stability is influenced by the size of the ring and the presence and positioning of substituents.
