**Step 2: Reaction Mechanism and Stereochemistry**

**Reaction Task:**
Predict the products and draw the mechanism of the reaction below, showing any relevant transition states. Additionally, name the reactant and the product properly indicating stereochemistry.

**Reactant:**
- A cyclohexane ring with a bromine (Br) atom attached at one position. The bromine is shown with a wedge, indicating it is coming out of the plane. Attached to the same carbon is a hydrogen, represented with a dash, indicating it is going into the plane. 

**Reagents:**
- Sodium ethoxide (NaOEt)
- Dimethyl sulfoxide (DMSO)

**Product:**
- Cyclohexene with a methyl group (CH₃) attached, represented with a wedge.

**Explanation:**
The reaction likely involves elimination, where the NaOEt acts as a base, removing the hydrogen atom that is anti to the bromine, leading to the formation of a double bond and the departure of the bromine atom as a leaving group. This results in the formation of cyclohexene with appropriate stereochemistry.
