Is `(CH_(2)-CH)_(n)` a homopolymer or a copolymer?

Explanation

To determine whether `(CH2-CH)n` is a homopolymer or a copolymer, we need to analyze the structure of the polymer and the type of monomeric units involved.

### Step-by-Step Solution:

1. **Identify the Monomeric Unit**:
The given polymer `(CH2-CH)n` can be recognized as being derived from the monomer ethylene, which has the structure CH2=CH2. In this notation, `n` indicates the number of repeating units of the monomer.

2. **Understand the Definition of Homopolymer**:
