Final answer:
Alcohols and ethers differ in their solubility in water due to hydrogen bonding and the number of carbon atoms. Butanol can form hydrogen bonds with water, while butane cannot. Propanol is more soluble in water than dipropyl ether because it can form more hydrogen bonds. Ethanol is more soluble in water than 1-hexanol due to its smaller carbon chain.
Step-by-step explanation:
1. Butanol can form hydrogen bonds with water, but butane cannot.
2. Propanol is more soluble than dipropyl ether because it can form more hydrogen bonds with water.
3. Ethanol is more soluble in water than 1-hexanol because it has fewer carbon atoms.
