![Figure 9-1 illustrates an SN2 substitution reaction involving the conversion of a bromohydride compound to a methoxy compound.
**Reactant (Q):**
- The starting compound (Q) features a bromine (Br) linked to a carbon atom. It has deuterium (D) and hydrogen (H) attached to adjacent carbon atoms.
**Reaction:**
- The substitution occurs through an SN2 mechanism with a methoxide ion (\( \text{CH}_3\text{O}^- \)) acting as the nucleophile. This results in the displacement of the bromine atom by the methoxy group (\( \text{OCH}_3 \)).
**Products:**
- Four potential stereoisomers are shown as products (A, B, C, and D), representing various configurations of the methoxy group, hydrogen, and deuterium around the carbon atom.
**Stereochemical Details:**
- **A:** The methoxy group is on a wedge, indicating a different stereochemical orientation compared to its position on the reactant.
- **B:** Shows an inverted stereochemical configuration compared to the reactant, common in SN2 reactions, where the methoxy group is opposite to the original bromine's position.
- **C:** Depicts another stereochemical inversion possibility.
- **D:** Further represents an alternative configuration, with the methoxy group on a wedge.
This reaction is an example of how different stereoisomers can be formed during nucleophilic substitution processes, with inversion of configuration being a key characteristic of the SN2 mechanism.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F53ee66c5-92fc-4868-ac88-c55611510c09%2Fcf1a4cd3-bab6-486c-97d4-c00c90af85d4%2Fctmsyc_processed.png&w=3840&q=75)

![**Question:**
*See Figure 9-1. The product of the S<sub>N</sub>2 reaction of Compound Q is*
**Options:**
- ○ A
- ○ B
- ○ C
- ○ D
**Explanation:**
Figure 9-1 is referenced in the question but not displayed here. The question likely refers to a multiple-choice assessment in which you must identify the correct product of an S<sub>N</sub>2 reaction involving Compound Q. An S<sub>N</sub>2 reaction is a bimolecular nucleophilic substitution reaction where the nucleophile attacks the electrophile from the opposite side, often resulting in an inversion of configuration.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F53ee66c5-92fc-4868-ac88-c55611510c09%2Fcf1a4cd3-bab6-486c-97d4-c00c90af85d4%2Ffvdod0q_processed.png&w=3840&q=75)
