Hydrolysis of ozonide of but-1-ene gives

Options

A. ethylene only
B. acetaldehyde and formaldehyde
C. propionaldehyde and formaldehyde
D. acetaldehyde only

Explanation

To solve the question regarding the hydrolysis of ozonide of but-1-ene, we can follow these steps:

### 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:
\[ \text{CH}_2=\text{CH-CH}_2-\text{CH}_3 \]

### Step 2: Ozonolysis of But-1-ene
When but-1-ene undergoes ozonolysis, it reacts with ozone (O3) to form an ozonide. The double bond in but-1-ene breaks, and two oxygen atoms are added, resulting in the formation of an ozonide. The ozonide structure can be represented as:
\[ \text{CH}_2-\text{CH}-\text{O}-\text{O}-\text{CH}_2-\text{CH}_3 \]

### Step 3: Hydrolysis of the Ozonide
The ozonide then undergoes hydrolysis, typically in the presence of a reducing agent like zinc dust (Zn). During hydrolysis, the ozonide reacts with water (H2O), breaking down into carbonyl compounds.

### Step 4: Identify the Products
The hydrolysis of the ozonide of but-1-ene results in the formation of two carbonyl compounds:
1. Propanal (C3H6O)
2. Formaldehyde (CH2O)

The reaction can be summarized as:
\[ \text{Ozonide} \xrightarrow{\text{H}_2\text{O}} \text{Propanal} + \text{Formaldehyde} \]

### Final Answer
Thus, the hydrolysis of ozonide of but-1-ene gives propanal and formaldehyde.
