Compare the following displacement reactions and account for any difference
(a) `ROH+NaBrto`
(b) `ROH+HBrto`

Explanation

To compare the displacement reactions of `ROH + NaBr` and `ROH + HBr`, we will analyze each reaction step by step.

### Step-by-Step Solution:

1. **Identify the Reactants**:
- In the first reaction, we have `ROH` (an alcohol) and `NaBr` (sodium bromide).
- In the second reaction, we have `ROH` (the same alcohol) and `HBr` (hydrobromic acid).
