Explanation

To determine which compounds will yield an isomer of 2,2-dimethylpropane upon catalytic hydrogenation, we need to analyze each given compound.

### Step-by-step Solution:

1. **Identify the structure of 2,2-dimethylpropane**:
- The molecular formula for 2,2-dimethylpropane is C5H12. It has a central carbon (C) bonded to two methyl groups (CH3) and two other carbons, making it a branched alkane.

2. **Analyze each compound**:
- **(1) `CH3CH = CH(CH3)CH3`**:
- This compound is 2-methylbut-2-ene. Upon catalytic hydrogenation, the double bond will be converted to a single bond, resulting in 2,2-dimethylpropane (C5H12).

- **(2) `CH3CH = CHCH3`**:
- This compound is but-2-ene. Upon hydrogenation, it will yield butane (C4H10), which is not an isomer of 2,2-dimethylpropane.

- **(3) `CH3C(H)=CHCH2CH3`**:
- This compound is 3-methyl-1-pentene. Upon hydrogenation, it will yield 2,2-dimethylpropane (C5H12) as well.

- **(4) `CH3(CH3)C=CH(CH3)C-CH3`**:
- This compound is 2,3-dimethylbut-2-ene. Upon hydrogenation, it will yield 2,2-dimethylpropane (C5H12) as well.

3. **Conclusion**:
- The compounds that will yield an isomer of 2,2-dimethylpropane upon catalytic hydrogenation are (1), (3), and (4).

### Final Answer:
The correct options are (1), (3), and (4).
