Secondary be akkyl halide among the following is

Options

A. 2-bromo-3methyl butane
B. 1-bromo-3methyl butane
C. 2-bromo-2methyl butane
D. 1-bromo-2methyl butane

Explanation

To determine which of the given options is a secondary alkyl halide, we need to understand the definition of secondary alkyl halides and analyze the structures of the provided compounds.

### Step 1: Understand Secondary Alkyl Halides
A secondary alkyl halide is defined as a compound where a halogen atom (like bromine or chlorine) is attached to a carbon atom that is itself attached to two other carbon atoms. This means the carbon with the halogen is a secondary carbon.

### Step 2: Analyze the Given Compounds
We need to evaluate the structures of the compounds mentioned in the question. Let's consider the examples provided in the video transcript:

1. **Butane with Bromine**:
- If we consider 1-bromobutane, the bromine is attached to a terminal carbon (C1), which is a primary carbon. Therefore, this is a primary alkyl halide.

2. **2-Bromo-2-methylbutane**:
- In this case, the bromine is attached to the second carbon of the butane chain, which is also attached to two other carbon atoms (the first and the third). This carbon is a secondary carbon, making this compound a secondary alkyl halide.

### Step 3: Conclusion
Based on the analysis, the secondary alkyl halide among the options given is **2-bromo-2-methylbutane**.

### Final Answer:
The secondary alkyl halide among the following is **2-bromo-2-methylbutane**.
