Question:
In the following reaction sequence:
II. Formation of B has proceeded with inversion.
Select the correct statement.
In the following reaction sequence:
II. Formation of B has proceeded with inversion.
Select the correct statement.
II. Formation of B has proceeded with inversion.
Select the correct statement.
Show Hint
S\(_N\)1: racemisation; S\(_N\)2: inversion; S\(_N\)1 at chiral centre gives racemic mixture.

- I and II
- Only I
- Only III
- None of these

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
S\(_N\)1 reactions give racemisation (via carbocation). S\(_N\)2 reactions give inversion of configuration.
Step 2: Detailed Explanation:
Formation of A via S\(_N\)1: carbocation intermediate, attack from either side \(\Rightarrow\) racemisation.
Formation of B via S\(_N\)2: backside attack \(\Rightarrow\) inversion.
Both statements I and II are correct.
Step 3: Final Answer:
Thus, both I and II are correct.
S\(_N\)1 reactions give racemisation (via carbocation). S\(_N\)2 reactions give inversion of configuration.
Step 2: Detailed Explanation:
Formation of A via S\(_N\)1: carbocation intermediate, attack from either side \(\Rightarrow\) racemisation.
Formation of B via S\(_N\)2: backside attack \(\Rightarrow\) inversion.
Both statements I and II are correct.
Step 3: Final Answer:
Thus, both I and II are correct.
