Give one example each of miscible liquid pairs showing positive and negative deviation from Raoult's law. Give one reason for each for such deviations.

Explanation

To answer the question regarding miscible liquid pairs that show positive and negative deviations from Raoult's law, we will provide examples along with reasons for each type of deviation.

### Step-by-Step Solution:

1. **Understanding Raoult's Law**:
Raoult's law states that the vapor pressure of a solvent in a solution is directly proportional to the mole fraction of the solvent. Deviations from Raoult's law occur when the interactions between different components in the mixture differ from the interactions in the pure components.

2. **Example of Positive Deviation**:
