Diethyl ether on warming with conc. `H_(2)SO_(4)` gives........

Explanation

To solve the question, we need to fill in the blank with the appropriate term based on the reaction of diethyl ether with concentrated sulfuric acid. Here’s the step-by-step solution:

### Step-by-Step Solution:

1. **Identify the Reactants**: The reactant in question is diethyl ether, which has the chemical formula \( CH_3CH_2OCH_2CH_3 \).

2. **Understand the Reaction Conditions**: The reaction takes place when diethyl ether is warmed with concentrated sulfuric acid (\( H_2SO_4 \)). Concentrated sulfuric acid acts as a strong acid and can protonate the ether.
