How will you convert Methyl amine into ethyl amine ?

Explanation

To convert methylamine (CH₃NH₂) into ethylamine (CH₃CH₂NH₂), we can follow a series of chemical reactions. Here is a step-by-step solution:

### Step 1: Convert Methylamine to Methanol
- **Reaction**: Treat methylamine (CH₃NH₂) with nitrous acid (HNO₂).
- **Equation**:
\[ \text{CH}_3\text{NH}_2 + \text{HNO}_2 \rightarrow \text{CH}_3\text{OH} + \text{N}_2 + \text{H}_2\text{O} \]
- **Product**: This reaction converts methylamine into methanol (CH₃OH).

### Step 2: Convert Methanol to Methyl Chloride
- **Reaction**: Treat methanol (CH₃OH) with phosphorus pentachloride (PCl₅).
- **Equation**:
\[ \text{CH}_3\text{OH} + \text{PCl}_5 \rightarrow \text{CH}_3\text{Cl} + \text{POCl}_3 + \text{HCl} \]
- **Product**: This reaction converts methanol into methyl chloride (CH₃Cl).

### Step 3: Convert Methyl Chloride to Methyl Cyanide
- **Reaction**: Treat methyl chloride (CH₃Cl) with sodium cyanide (NaCN).
- **Equation**:
\[ \text{CH}_3\text{Cl} + \text{NaCN} \rightarrow \text{CH}_3\text{CN} + \text{NaCl} \]
- **Product**: This reaction converts methyl chloride into methyl cyanide (CH₃CN).

### Step 4: Reduce Methyl Cyanide to Ethylamine
- **Reaction**: Treat methyl cyanide (CH₃CN) with hydrogen (H₂) in the presence of a nickel catalyst.
- **Equation**:
\[ \text{CH}_3\text{CN} + 2\text{H}_2 \xrightarrow{\text{Ni}} \text{CH}_3\text{CH}_2\text{NH}_2 \]
- **Product**: This reduction converts methyl cyanide into ethylamine (CH₃CH₂NH₂).

### Final Product
- After these series of reactions, we have successfully converted methylamine (CH₃NH₂) into ethylamine (CH₃CH₂NH₂).
