Out of HCl (g) and `SOCI_(2)` which is preferred for converting ethanol into chloroethane?

Explanation

To determine which reagent is preferred for converting ethanol (C2H5OH) into chloroethane (C2H5Cl), we will analyze the reactions with both HCl and SOCl2.

### Step-by-Step Solution:

1. **Identify the Reaction**:
- We want to convert ethanol (C2H5OH) into chloroethane (C2H5Cl).
- This is a substitution reaction where the hydroxyl (OH) group in ethanol is replaced by a chlorine (Cl) atom.
