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.
![### Chemistry Quiz Question
#### Question 26 of 31
The chemical structure of a biologically relevant molecule is shown below. Which functional group is NOT present?
**[Diagram of Molecule]**: The diagram features a complex organic molecule consisting of multiple hexagonal rings and chains. The molecule includes various bonds and elements indicating different functional groups.
---
**Options:**
A) Alkene
B) Alkyl chain
C) Cyclohexane ring
D) Aromatic ring
E) Alcohol
---
Take a close look at the molecular structure and identify the functional groups present to determine which one is missing.
Submit your answer to move to the next question.
**Note:** Understanding the basic functional groups in organic compounds will help immensely in solving this type of question. An alkene contains a carbon-carbon double bond, an alkyl chain consists of hydrogen and carbon atoms arranged in a chain, a cyclohexane ring is a six-carbon ring without double bonds, an aromatic ring contains conjugated pi electrons (like benzene), and alcohols contain an -OH group attached to a carbon atom.
