Write the structure and give `IUPAC` name of the alkane which gives only Pentan-`2`-one on reductive ozonolysis,

Explanation

To solve the problem, we need to identify the structure of the alkane that, upon reductive ozonolysis, yields only Pentan-2-one.

### Step-by-Step Solution:

1. **Understanding Ozonolysis**: Ozonolysis is a reaction where alkenes are cleaved by ozone (O₃) to form carbonyl compounds. In reductive ozonolysis, the products are typically aldehydes or ketones, depending on the structure of the alkene.

2. **Identifying the Target Product**: The target product is Pentan-2-one, which has the structure:
