Explanation

To find the major product of the given reaction, we can follow these steps:

### Step 1: Identify the Reactants
We have a tertiary alkyl halide (specifically, a tertiary chloride) and a strong base, which is potassium tert-butoxide (KOC(CH₃)₃).

### Step 2: Determine the Mechanism
Given that we have a tertiary alkyl halide and a strong base, the reaction will likely proceed via the E2 elimination mechanism. In this mechanism, the base abstracts a proton from the β-carbon while the leaving group (Cl) departs simultaneously.

### Step 3: Identify the β-Hydrogens
In the structure of the tertiary alkyl halide, we need to identify the β-hydrogens. The β-carbon is the carbon adjacent to the carbon bonded to the chlorine. In this case, we have multiple β-hydrogens available for abstraction.

### Step 4: Base Abstraction
The strong base (potassium tert-butoxide) will abstract one of the β-hydrogens. The choice of which β-hydrogen to abstract can influence the product, but in this case, we will consider the most accessible β-hydrogen.

### Step 5: Formation of the Alkene
As the base abstracts the β-hydrogen, the bond between the β-carbon and the hydrogen will break, and the bond between the α-carbon (the carbon attached to the chlorine) and the chlorine will also break, resulting in the formation of a double bond between the α and β-carbons.

### Step 6: Naming the Product
After the elimination reaction, we will have an alkene. The product will be a substituted alkene. We can name the product based on the position of the double bond and the substituents:
- The product formed will be 2-methylpropene (or 2-methylprop-1-ene).

### Final Product
The major product of the reaction is **2-methylpropene**.
