Assertion: tert-Butyl bromide undergoes Wurtz reaction to give 2,2,3,3-tetramethylbutane.
Reason: In Wurtz reaction, alkyl halides react with sodium in dry ether to give hydrocarbon containing double the number of carbon atoms present in the halide.

Options

A. Assertion and reason both are correct and reason is correct explanation of assertion.
B. Assertion and reason are both are wrong statements
C. Assertion is correct but reason is wrong
D. Assertion is wrong but reason is correct statement.

Explanation

To solve the question regarding the assertion and reason related to tert-butyl bromide and the Wurtz reaction, we will analyze both statements step by step.

### Step 1: Understanding the Assertion
The assertion states that tert-butyl bromide undergoes a Wurtz reaction to give 2,2,3,3-tetramethylbutane.

- **Analysis**: Tert-butyl bromide (C4H9Br) is a tertiary alkyl halide. In a typical Wurtz reaction, alkyl halides react with sodium in dry ether to form alkanes. However, tertiary alkyl halides often do not undergo Wurtz reaction due to steric hindrance. Instead, they tend to undergo elimination reactions, leading to the formation of alkenes rather than alkanes.

### Step 2: Understanding the Reason
The reason states that in the Wurtz reaction, alkyl halides react with sodium in dry ether to give hydrocarbons containing double the number of carbon atoms present in the halide.

- **Analysis**: This statement is generally true. In a Wurtz reaction, when two alkyl halides react with sodium, they can couple to form a hydrocarbon that has twice the number of carbon atoms as the original alkyl halides. For example, if we take two molecules of a bromoalkane (C2H5Br), they can combine to form butane (C4H10).

### Step 3: Conclusion
- **Assertion**: The assertion is **incorrect** because tert-butyl bromide does not undergo the Wurtz reaction due to steric hindrance; it leads to elimination reactions instead.
- **Reason**: The reason is **correct** as it accurately describes the Wurtz reaction mechanism.

### Final Answer
- Assertion is **false**.
- Reason is **true**.
