Write structures of different chain isomers of alkanes corresponding to the molecular formula `C_(6)H_(14)` Write their IUPAC names and classify each carbon atom as `1^(@), 2^(@), 3^(@)` or `4^(@)`.

Explanation

To solve the problem of finding different chain isomers of alkanes corresponding to the molecular formula \(C_6H_{14}\), we will follow a step-by-step approach to identify the structures, name them using IUPAC nomenclature, and classify each carbon atom based on its degree.

### Step 1: Identify the Molecular Formula
The molecular formula given is \(C_6H_{14}\). This indicates that we are dealing with an alkane, which means it is a saturated hydrocarbon with no rings or double bonds.

### Step 2: Determine the Degree of Unsaturation
For alkanes, the degree of unsaturation is calculated using the formula:
\[
