### IUPAC Naming and SN1 Reaction Analysis

**Task:** Select the correct IUPAC name for the following organic substrate, including the \( R \) or \( S \) designation where appropriate, and draw the major organic product(s) for the \( S_N1 \) reaction. Include wedge-and-dash bonds and draw hydrogen on a stereocenter.

#### Structure Description
- The given molecule is a brominated hydrocarbon with a chiral center.
- A bromine (Br) atom is attached to the second carbon in the carbon chain.
- The molecule also has methyl (\( CH_3 \)) groups attached, making it a dimethylpentane derivative.
- The image indicates interaction with water (\( H_2O \)), suggesting an \( S_N1 \) reaction mechanism.

#### Graphical Interface
- The right side features a drawing tool for constructing reaction products.
- The toolbar includes options for drawing bonds (wedge, dash) and adding atoms (C, H, O).

#### IUPAC Naming Options:
1. 3-bromo-2,3-dimethylpentane
2. \( (R) \)-3-bromo-2,3-dimethylpentane
3. 3-bromo-3,4-dimethylpentane
4. \( (S) \)-3-bromo-3,4-dimethylpentane

----

#### Explanation of Concepts:

- **\( S_N1 \) Reaction:** A unimolecular nucleophilic substitution where the rate-determining step involves breaking the bond to the leaving group (Br in this case) resulting in a carbocation, followed by a reaction with a nucleophile (water).
  
- **Stereochemistry (R/S):** The configuration of chiral centers can be designated as \( R \) (rectus, right) or \( S \) (sinister, left) depending on the spatial arrangement of substituents.

- **Drawing Wedge-and-Dash Bonds:** Used to represent three-dimensional structure. A wedge signifies a bond coming out of the plane towards the observer, a dash indicates a bond going behind the plane.

By analyzing the structure and using the toolbar, the user can hypothesize the reaction mechanism and predict the product's structure.
