Catalysis and Enzymatic Reactions

Catalysis is the kind of chemical reaction in which the rate (speed) of a reaction is enhanced by the catalyst which is not consumed during the process of reaction and afterward it is removed when the catalyst is not used to make up the impurity in the product. The enzymatic reaction is the reaction that is catalyzed via enzymes.

Lock And Key Model

The lock-and-key model is used to describe the catalytic enzyme activity, based on the interaction between enzyme and substrate. This model considers the lock as an enzyme and the key as a substrate to explain this model. The concept of how a unique distinct key only can have the access to open a particular lock resembles how the specific substrate can only fit into the particular active site of the enzyme. This is significant in understanding the intermolecular interaction between proteins and plays a vital role in drug interaction.

Question

**Transcription for Educational Website**

**Task:**

Determine the mechanistic pathway and product(s) for the reaction. Justify your responses using the four (4) criteria. Be specific with respect to configuration and major/minor product mixtures where appropriate.

**Chemical Reaction:**

The diagram displays the structure of 2-bromo-2-methylbutane reacting with sodium acetate (NaOAc) in the presence of DMSO (dimethyl sulfoxide). The molecular structure of 2-bromo-2-methylbutane includes a central carbon bound to a bromine atom (Br), two methyl groups (CH₃), and an ethyl group (CH₂CH₃).

**Mechanism Explanation:**

Based on the structure and conditions:
- **Elimination vs. Substitution:** The presence of a strong base like sodium acetate in DMSO, a polar aprotic solvent, suggests involvement of an elimination mechanism (E2).
- **Product Prediction:** The reaction is likely to form an alkene as the major product by removing a hydrogen atom beta to the bromine, leading to the formation of the more stable alkene according to Zaitsev's rule.
- **Stereochemistry:** Consideration of stereochemistry (cis/trans or E/Z isomerism) is necessary to predict the major and minor alkene products.

The analysis involves predicting whether Zaitsev’s or Hofmann rule predominates and may require drawing possible alkene structures resulting from the elimination.

This type of reaction exemplifies common elimination processes in organic chemistry, highlighting the importance of base strength, leaving groups, and solvent effects on mechanism and product outcome.
