Ethers have low solubility in water but high solubility in conc. `H_(2)S_(4)`. Explain.

Explanation

### Step-by-Step Solution:

1. **Understanding Ethers**: Ethers are organic compounds with the general formula ROR', where R and R' are alkyl or aryl groups. They contain an oxygen atom bonded to two carbon atoms.

2. **Solubility in Water**: Ethers have low solubility in water due to their inability to form strong hydrogen bonds with water molecules. Although ethers have an oxygen atom that can participate in hydrogen bonding, the presence of two hydrocarbon groups (R and R') reduces their overall polarity. This makes them less compatible with the polar nature of water.

3. **Solubility in Concentrated H2SO4**: In contrast, ethers are highly soluble in concentrated sulfuric acid (H2SO4). This is because sulfuric acid is a strong acid and can donate protons (H⁺ ions). The oxygen atom in ethers has a lone pair of electrons, which can readily accept a proton from H2SO4.
