Oxidation state of oxygen is + 1 in .......... And +2 in ,.......

Explanation

To determine the oxidation states of oxygen in different compounds, we need to analyze the compounds where oxygen can exhibit positive oxidation states.

### Step-by-Step Solution:

1. **Understanding Oxidation States**:
- The oxidation state of an element in a compound indicates the degree of oxidation (loss of electrons) of that element. Oxygen typically has a negative oxidation state, usually -2. However, in some compounds, it can exhibit positive oxidation states.

2. **Identifying Conditions for Positive Oxidation States**:
