What is the relationship between the members of following pairs of structures? Are they structural or geometrical isomers or resonance contributors?
`H- overset(overset(+)OH) overset(||)C-OH " " H - overset(OH) overset(|) (C ^+) -OH`

Explanation

To determine the relationship between the given pairs of structures, we need to analyze their characteristics and see if they are structural isomers, geometrical isomers, or resonance contributors.

### Step-by-Step Solution:

1. **Identify the Structures**:
- The first structure can be represented as:
\[
H - \overset{+}{OH} - C = O - H
