What is the hyper-conjugation? Which is the most stable among the following?
`CH_(3)overset(*)(CH_(2)),overset()((CH_(3))_(3))overset(*)(C), (CH_(3))_(2)overset(*)(C)H`

Explanation

### Step-by-Step Solution:

1. **Understanding Hyperconjugation**:
- Hyperconjugation is a stabilizing interaction that results from the overlap of a σ-bond (sigma bond) with an adjacent empty p-orbital or a π-bond (pi bond). This interaction allows for the delocalization of electrons, which can stabilize the molecule.

2. **Identifying the Given Compounds**:
- The compounds given in the question are:
1. `CH₃-CH₂-CH(•)-CH₃` (Compound 1)
