Select the correct IUPAC name for the following organic substrate, including the or designation where appropriate, and draw the major organic product(s) for the 1 reaction. Include wedge-and-dash bonds and draw hydrogen on a stereocenter.
The correct answer and explanation is :
To provide an accurate IUPAC name, major product, and a well-explained mechanism for the SN1 reaction, I need the structural details of the organic substrate. If you can upload an image or describe the molecular structure (e.g., molecular formula, functional groups, stereochemistry), I will generate the correct IUPAC name and reaction mechanism.
However, in general, an SN1 reaction follows these key principles:
Mechanism Overview
- Carbocation Formation (Rate-Determining Step):
The leaving group departs, forming a carbocation (which is planar and allows for rearrangements). - Nucleophilic Attack:
The nucleophile (usually a weak base like water or an alcohol) attacks the carbocation from either side, leading to a racemic mixture if the starting material is chiral. - Product Formation:
If the reaction occurs in a protic solvent, solvolysis (reaction with the solvent) may occur, forming an ether or alcohol product.
Key Factors Favoring SN1
- Tertiary or secondary alkyl halides (due to carbocation stability).
- Good leaving groups (e.g., Cl⁻, Br⁻, I⁻, TsO⁻).
- Protic solvents (e.g., H₂O, ethanol, methanol).
Expected Product
- If the substrate has a stereocenter, the product will likely be racemic due to the planar intermediate.
- Rearrangement may occur if a more stable carbocation can form.
