Form among the following choose the solutions with positive and negative deviations
(1) ROH+ROR
(2) RSH+ROR
(3) `CHCl_(3)+CH_(3)COCH_(3)`
(4) HF+ROH

Explanation

To determine which solutions exhibit positive and negative deviations from Raoult's law, we need to analyze the interactions between the components in each solution.

### Step-by-Step Solution:

1. **Understanding Positive and Negative Deviations**:
- **Positive Deviation**: Occurs when the vapor pressure of the solution is higher than predicted by Raoult's law. This happens when the solute-solute and solvent-solvent interactions are stronger than the solute-solvent interactions.
- **Negative Deviation**: Occurs when the vapor pressure of the solution is lower than predicted. This happens when the solute-solvent interactions are stronger than the solute-solute and solvent-solvent interactions.
