Predict the structure of a hydrocarbon which gives one mole each of ethanedial and butanedial on ozonolysis.

Explanation

To predict the structure of a hydrocarbon that gives one mole each of ethanedial and butanedial on ozonolysis, we can follow these steps:

### Step 1: Understand the Products
We know that the products of ozonolysis are:
- Ethanedial (C2H2O2), which has the structure:
\[ O=C=O \]
