Classify the following species into Lewis acids and Lewis bases and show how these act as Lewis acid`//`base:
a. `overset(Θ)(O)H, b. F^(Θ), c. H^(o+), d. BCl_(3)`

Explanation

To classify the given species into Lewis acids and Lewis bases, we first need to understand the definitions:

- **Lewis Acid**: A species that can accept a pair of electrons (electron pair acceptor).
- **Lewis Base**: A species that can donate a pair of electrons (electron pair donor).

Now, let's analyze each species one by one:

### Step 1: Analyze `OH^-` (Hydroxide Ion)
