### Determining the Name of a Compound Using Newman Projections

Newman projections are a way of visualizing the conformation of a molecule, especially around its carbon-carbon bonds, by looking straight down the bond between two carbon atoms. Below are a series of Newman projections for a particular compound. We aim to determine the name of the compound based on these projections.

#### Newman Projections:

1. **Projection I:** 
   - Front carbon: one hydrogen (H), one methyl (CH₃) group, one ethyl (CH₂CH₃) group in a staggered conformation.
   - Back carbon: three hydrogens (H).
     
2. **Projection II:**
   - Front carbon: one hydrogen (H), one methyl (CH₃) group, one ethyl (CH₂CH₃) group in a staggered conformation.
   - Back carbon: three hydrogens (H).

3. **Projection III:**
   - Front carbon: one hydrogen (H), one methyl (CH₃) group, one ethyl (CH₂CH₃) group in a staggered conformation.
   - Back carbon: three hydrogens (H).

4. **Projection IV:**
   - Front carbon: one hydrogen (H), one methyl (CH₃) group, one ethyl (CH₂CH₃) group in a staggered conformation.
   - Back carbon: three hydrogens (H).

5. **Projection V:**
   - Front carbon: one hydrogen (H), one methyl (CH₃) group, one ethyl (CH₂CH₃) group in a staggered conformation.
   - Back carbon: three hydrogens (H).

6. **Projection VI:**
   - Front carbon: one hydrogen (H), one methyl (CH₃) group, one ethyl (CH₂CH₃) group in a staggered conformation.
   - Back carbon: three hydrogens (H).

#### Brief Analysis:

All the Newman projections shown are staggered conformations of the same molecule, typically representing the lowest energy form.

#### Conclusion:

From the Newman projections, we can infer that the compound is **butane (C₄H₁₀)**. It is the simplest compound that fits the pattern of displaying Newman projections shown, specifically focusing on rotations and interactions around the carbon-carbon single bonds. 

Therefore
