Which one represents eclipsed hexane?

The image displays three Newman projections of alkanes, demonstrating different conformations and substituents attached to the central carbon atom:

1. **First Structure:**
   - The circle represents the front carbon atom of the alkane.
   - Substituents: 
     - CH₃ (methyl group) pointing upward
     - H (hydrogen) on the left
     - CH(CH₃)₂ (isopropyl group) on the right

2. **Second Structure:**
   - Similar circle representing the front carbon atom.
   - Substituents:
     - CH₃ (methyl group) pointing upward
     - H (hydrogen) on the left
     - CH(CH₃)₂ (isopropyl group) on the right
     - CH₃ (methyl group) on the bottom right
     - H (hydrogen) on the bottom left 

3. **Third Structure:**
   - Circle showing the front carbon atom.
   - Substituents:
     - CH₃ (methyl group) pointing upward
     - H (hydrogen) on the left
     - (H₃C)₂HC (isopropyl group) on the right

These structures illustrate the spatial arrangement of the groups around the carbon atom in Newman projections. The projection helps in visualizing the stereochemistry of the compounds and understanding their possible conformations.
