Ethers, like alcohols, show similar miscibility with water due to the ability of the oxygen atom in ethers to form hydrogen bonds with water molecules. The observed miscibility, exemplified by ethoxyethane and butan-1-ol, contrasts with the immiscibility of pentane with water.
How does the miscibility of ethers with water compare to that of alcohols, and what role does hydrogen bonding play in the observed miscibility?

Ethers are generally less miscible with water compared to alcohols. While both ethers and alcohols can form hydrogen bonds with water, alcohols tend to have stronger and more extensive hydrogen bonding due to the presence of the hydroxyl group. The hydroxyl group in alcohols readily participates in hydrogen bonding with water molecules, enhancing their solubility. In contrast, ethers, having only a less polar C-O-C linkage, exhibit weaker hydrogen bonding and reduced miscibility with water. The stronger hydrogen bonding in alcohols contributes to their greater solubility and miscibility in aqueous environments compared to ethers.
