**Title: Understanding the Systematic (IUPAC) Naming of Alkanes**

**Description:**

The image presents a structural formula of an organic compound, which is a part of the alkane family. The task is to determine the systematic (IUPAC) name for this compound.

**Molecular Structure Details:**

1. **Central Carbon Atom Arrangement:**
   - The structure consists of a central carbon atom bonded to three other carbon atoms.
   
2. **Alkyl Groups:**
   - One of these carbon atoms is bonded to two hydrogen atoms (CH₃), representing a methyl group.
   - Another carbon atom is bonded to two hydrogen atoms (CH₂).
   - The third carbon atom, also a CH₃ group, is attached directly to the central carbon atom.

3. **Chemical Structure Explanation:**
   - The compound includes four carbon atoms in total.
   - The main carbon chain has three carbon atoms with a single methyl group branching off the second carbon.

**IUPAC Naming Convention:**

Using IUPAC nomenclature rules for alkanes, the longest carbon chain is identified and named, and substituents are assigned numbers based on their position along the chain:

- The longest continuous chain of carbon atoms consists of three carbons, named "propane."
- There is a methyl group (CH₃) attached to the second carbon of the propane chain.

Hence, the compound is named:

**2-Methylpropane**

This name indicates a propane chain with a methyl group substitution at the second carbon. This is also commonly known as isobutane.
