Maximum number of structural isomers for a pentane with molecular formula `C_(5)H_(12)` is

Explanation

To determine the maximum number of structural isomers for pentane with the molecular formula C₅H₁₂, we will follow these steps:

### Step-by-Step Solution:

1. **Understanding Structural Isomers**:
Structural isomers are compounds that have the same molecular formula but different structural arrangements of atoms. For pentane (C₅H₁₂), we need to find different ways to arrange the five carbon atoms and the associated hydrogen atoms.

2. **Identify the Straight Chain Isomer**:
