A hydrocarbon decolourised bromine water. On ozonolysis it gives 3-methyl butanal and acetaldehyde. Write the structure of the hydrocarbon.

Explanation

To determine the structure of the hydrocarbon that decolourises bromine water and gives 3-methylbutanal and acetaldehyde upon ozonolysis, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Type of Hydrocarbon**:
- The hydrocarbon decolourises bromine water, indicating that it is an unsaturated hydrocarbon (either an alkene or an alkyne).

2. **Analyze the Products of Ozonolysis**:
