Which of the following reagents can be used to convert alkyl halide into alkane ?

Options

A. Action of Grignard reagent
B. Action of `Bu_(3)SnH`
C. Action of superacid
D. Action of `K^(+)O^(-)C(CH_(3))`

Answer

To convert an alkyl halide into an alkane, we typically use a reducing agent. Here’s a step-by-step solution to identify the appropriate reagent:

### Step 1: Understand the Reaction
Alkyl halides (R-X, where X is a halogen) can be converted into alkanes (R-H) through a reduction reaction. This involves the removal of the halogen atom and the addition of hydrogen.

### Step 2: Identify Suitable Reducing Agents
Common reducing agents that can be used to convert alkyl halides into alkanes include:
- Zinc (Zn) in the presence of an acid (HCl)
- Lithium aluminum hydride (LiAlH4)
- Tributyltin hydride (Bu3SnH)

### Step 3: Select the Most Commonly Used Reagent
Among the listed reducing agents, tributyltin hydride (Bu3SnH) is often used in organic synthesis for this purpose. It effectively reduces alkyl halides to alkanes.

### Step 4: Write the Reaction
The general reaction can be represented as follows:
\[ R-X + \text{Reducing Agent} \rightarrow R-H + \text{by-products} \]
For example, if we take an alkyl halide like bromoethane (C2H5Br) and treat it with tributyltin hydride, we would get ethane (C2H6) as the product.

### Conclusion
The reagent that can be used to convert alkyl halides into alkanes is **Tributyltin hydride (Bu3SnH)**.
