Why a non-symmetrical ether is not prepared by heating a mixture of ROH and R'OH in acid.

Explanation

To understand why a non-symmetrical ether cannot be prepared by heating a mixture of ROH (alcohol) and R'OH (another alcohol) in an acidic medium, we can break down the process step by step.

### Step-by-Step Solution:

1. **Understanding Ethers Formation**: Ethers can be formed through the reaction of two alcohols in the presence of an acid. The general reaction involves the dehydration of alcohols to form ethers.

2. **Acidic Medium**: When we add an acid (H⁺) to the alcohols, it protonates the hydroxyl group (-OH) of the alcohol, making it a better leaving group.
