**Question 18: Which of the following represents the correct graph for the SN2 reaction?****Graph Descriptions:**- **Graph (a):** - The vertical axis is labeled "log (rate)." - The horizontal axis lists bromides: CH3–Br, CH3–CH2–Br, CH3–CH–Br with a CH3 group, and CH3–C–Br with two CH3 groups. - The graph shows a decreasing curve, indicating a decline in the reaction rate with increasing steric hindrance.- **Graph (b):** - The vertical axis is labeled "log (rate)." - The horizontal axis lists bromides: CH3–Br, Et–Br, i–Pr–Br, t–Bu–Br. - The graph is a straight line, indicating a constant reaction rate regardless of the substrate.- **Graph (c):** - The vertical axis is labeled "log (rate)." - The horizontal axis lists bromides: CH3–Br, Et–Br, i–Pr–Br (isopropyl), t–Bu–Br. - The graph shows an increasing curve, suggesting that the reaction rate increases with increased steric hindrance.- **Graph (d):** - The vertical axis is labeled "log (rate)." - The horizontal axis lists bromides: CH3–Br, Et–Br, i–Pr–Br, t–Bu–Br. - The graph shows a wavy pattern, suggesting no clear trend in reaction rate.The correct graph for an SN2 reaction would likely be one that demonstrates decreased reaction rate with increased steric hindrance due to the backside attack mechanism of SN2 reactions.

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.
