Ethyl cyanide (A) can be converted to ethyl amine (B) by:

Options

A. `A overset(Sn //HCI)rarr B`
B. `A overset(H_(3)O^(+))rarr overset(NH_(3)//Delta)rarr overset(KBrO //Delta)rarr B`
C. `A overset(LiAIH_(4))rarr B`
D. both (a),(c) are correct

Answer

To convert ethyl cyanide (A) to ethyl amine (B), we can follow these steps:

### Step 1: Identify the Structures
- Ethyl cyanide (A) is represented as CH3CH2CN.
- Ethyl amine (B) is represented as CH3CH2NH2.

### Step 2: Reduction of Ethyl Cyanide
- Ethyl cyanide can be reduced to an intermediate compound. The first step involves the reduction of the cyano group (CN) to an amine group (NH2).
- This can be achieved using a reducing agent such as lithium aluminum hydride (LiAlH4) or hydrogen in the presence of a catalyst.

### Step 3: Formation of Ethyl Amine
- The reduction of ethyl cyanide (CH3CH2CN) will yield ethyl amine (CH3CH2NH2) as the final product.
- The reaction can be summarized as follows:
\[ \text{CH}_3\text{CH}_2\text{CN} + 2 \text{H} \rightarrow \text{CH}_3\text{CH}_2\text{NH}_2 \]

### Conclusion
Thus, ethyl cyanide (A) can be converted to ethyl amine (B) through a reduction reaction.
