Question: In the mechanism of the SN2 reaction, which of the following statements is true?

Options:

Correct Answer: The nucleophile attacks from the opposite side of the leaving group.

Solution:

In an SN2 reaction, the nucleophile attacks the substrate from the side opposite to the leaving group, leading to a backside attack.

In the mechanism of the SN2 reaction, which of the following statements is true?

In the mechanism of the SN2 reaction, which of the following statements is true?

Step 1: Understand what an SN2 reaction is. It is a type of chemical reaction where one molecule replaces another.
Step 2: Identify the key players in the reaction: the nucleophile (the attacking molecule) and the substrate (the molecule being attacked).
Step 3: Recognize that the leaving group is the part of the substrate that will be replaced.
Step 4: Learn that in an SN2 reaction, the nucleophile approaches the substrate from the side opposite to the leaving group.
Step 5: Understand that this approach is called a 'backside attack' because the nucleophile comes in from the back side of the substrate.

SN2 Mechanism – The SN2 reaction involves a nucleophile attacking a substrate from the opposite side of the leaving group, resulting in a concerted mechanism.
Backside Attack – The term 'backside attack' refers to the nucleophile approaching the electrophilic carbon from the side opposite to the leaving group, which is crucial for the reaction to proceed.
