Question
**Reaction Prediction with Intermediate Steps**

**Objective:**
Consider the following reaction. Predict all products and determine which one is the major product. Draw the intermediate leading to the product(s).

**Reaction Conditions:**
- Reactant: 2-bromo-2-methylpropane
- Reagent: Ethanol (CH₃CH₂OH)
- Conditions: Heat

**Description:**
This reaction involves heating 2-bromo-2-methylpropane with ethanol. We need to predict the possible products and identify the major product. Additionally, we are required to illustrate the intermediate structure(s) formed during the reaction process.

**Explanation:**
1. The initial reactant is 2-bromo-2-methylpropane, which is a tertiary alkyl halide.
2. When heated in the presence of ethanol, an elimination reaction (E2 or E1) is likely to occur, leading to the formation of alkenes.

**Intermediates and Products:**
- The reaction may form a carbocation intermediate if it follows an E1 mechanism.
- Alternatively, a concerted mechanism without an intermediate could occur through an E2 pathway.

**Major Product:**
- The major product will be determined based on the stability of the possible alkenes formed.

**Visual Explanation:**
- The structure of 2-bromo-2-methylpropane is shown with a bromine atom attached to the second carbon which is tertiary.
- The mechanism involves either the formation of a carbocation (E1) or a single-step elimination (E2), leading to the formation of the major alkene product.
  
**Concluding Step:**
Combine this theoretical knowledge with practical laboratory observations to experiment and confirm the predicted major product.
