Question

In $\mathrm{S}_{\mathrm{N}}1$ reaction, the racemization takes place. It is due to

• A. inversion of configuration
• B. retention of configuration
• C. conversion of configuration
• D. Both (a) and (b)

Hint:

$\mathrm{S_N1}$ proceeds via a planar carbocation intermediate, leading to racemic mixture.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
$\mathrm{S_N1}$ proceeds via a carbocation intermediate.
Step 2: Detailed Explanation:
In $\mathrm{S_N1}$ reactions, the carbocation intermediate is planar, leading to attack from both sides, resulting in both inversion and retention, hence racemization.
Step 3: Final Answer:
Racemization occurs due to both inversion and retention.
