But-1-ene may be converted to butane by reaction with

Options

A. Zn-HCI
B. Sn-HCI
C. Zn-Hg
D. `Pd//H_2`

Answer

To convert but-1-ene to butane, we can use hydrogen gas in the presence of a palladium catalyst. Here’s a step-by-step breakdown of the process:

### Step 1: Understand the Structure of But-1-ene
But-1-ene is an alkene with the formula C4H8. Its structure can be represented as:
\[ \text{CH}_2=\text{CH}-\text{CH}_2-\text{CH}_3 \]
This shows a double bond between the first and second carbon atoms.

### Step 2: Identify the Reaction Type
The conversion of but-1-ene to butane involves the addition of hydrogen (H2) across the double bond. This process is known as hydrogenation.

### Step 3: Set Up the Reaction
To carry out the hydrogenation, we need to react but-1-ene with hydrogen gas (H2) in the presence of a catalyst, which in this case is palladium (Pd).

### Step 4: Write the Reaction Equation
The reaction can be represented as follows:
\[ \text{CH}_2=\text{CH}-\text{CH}_2-\text{CH}_3 + \text{H}_2 \xrightarrow{\text{Pd}} \text{CH}_3-\text{CH}_2-\text{CH}_2-\text{CH}_3 \]
This shows that but-1-ene reacts with hydrogen gas in the presence of palladium to yield butane (C4H10).

### Step 5: Conclusion
The final product of the reaction is butane, which is an alkane with the formula C4H10. Thus, but-1-ene can be converted to butane by the reaction with hydrogen gas in the presence of palladium.

### Final Answer
But-1-ene may be converted to butane by reaction with hydrogen gas in the presence of palladium.
