Can you please help which of these statement is true?
### Question on S_N1 Reactions Which statements is/are true about an S_N1 reaction? I. Occurs through a carbocation intermediate. II. Sometimes occurs with rearrangement of the carbon skeleton. III. Occurs solely with inversion of configuration at the center undergoing substitution. **Options:** - O I, II, and III - O **I and II** - O I and III - O I only **Explanation:** This question tests the understanding of the S_N1 reaction mechanism in organic chemistry. Let's break down the statements one by one: 1. **Statement I: Occurs through a carbocation intermediate.** - This is a fundamental aspect of the S_N1 mechanism. In an S_N1 reaction, the first step involves the loss of the leaving group to form a carbocation intermediate. This intermediate is crucial for the reaction progress. 2. **Statement II: Sometimes occurs with rearrangement of the carbon skeleton.** - This statement is also true. The carbocation intermediate formed during an S_N1 reaction is often prone to rearrangement. The rearrangement occurs to form a more stable carbocation (e.g., a shift from a secondary to a tertiary carbocation). 3. **Statement III: Occurs solely with inversion of configuration at the center undergoing substitution.** - This statement is false for S_N1 reactions. In an S_N1 reaction, the product is typically a racemic mixture due to the planar nature of the carbocation intermediate. This allows for both retention and inversion of configuration, not solely inversion. Therefore, the correct answer is **I and II**.
