Aldehydes react with alcohols in presence of dry hydrogen chloride to form_______.

Explanation

### Step-by-Step Solution:

1. **Understanding the Reactants**:
- Aldehydes and alcohols are the two reactants in this reaction. Aldehydes have the general formula RCHO, where R is a hydrocarbon group. Alcohols have the general formula R'OH, where R' is also a hydrocarbon group.

2. **Presence of Dry Hydrogen Chloride (HCl)**:
- Dry hydrogen chloride acts as a catalyst in this reaction. It helps in the formation of a more reactive intermediate by protonating the carbonyl oxygen of the aldehyde.
