C. `HCI and CI_(2)O`
D. `HCI and HCIO_(3)`

Explanation

To determine the products expected from the disproportionation reaction of hypochlorous acid (HClO), we can follow these steps:

### Step-by-Step Solution:

1. **Understand Disproportionation Reaction**:
A disproportionation reaction is a type of redox reaction where a single substance is both oxidized and reduced, forming two different products. In this case, we will analyze hypochlorous acid (HClO).

2. **Identify the Reactant**:
The reactant in this case is hypochlorous acid, which has the chemical formula HClO.

3. **Determine Oxidation States**:
In HClO, chlorine (Cl) has an oxidation state of +1. During disproportionation, it can be oxidized to a higher oxidation state and reduced to a lower oxidation state.

4. **Products Formation**:
- When Cl in HClO is oxidized, it can form chlorate ion (ClO3^-), where Cl has an oxidation state of +5.
- When Cl in HClO is reduced, it can form hydrochloric acid (HCl), where Cl has an oxidation state of -1.

5. **Write the Balanced Reaction**:
The balanced disproportionation reaction can be represented as:
\[ 3 \, \text{HClO} \rightarrow 2 \, \text{HCl} + \text{ClO}_3^- \]
This shows that three moles of hypochlorous acid yield two moles of hydrochloric acid and one mole of chlorate ion.

6. **Final Products**:
The expected products from the disproportionation reaction of hypochlorous acid are hydrochloric acid (HCl) and chlorate ion (ClO3^-).

### Conclusion:
The products expected from the disproportionation reaction of hypochlorous acid (HClO) are hydrochloric acid (HCl) and chlorate ion (ClO3^-).
