Solution
Which compound would have the higher boilingpoint, ethyl methyl ether or 1-propanol? Explain.
1-propanol has 3 carbon atoms, and can form hydrogen bonds with water giving it a higher boiling point.
Ethyl methyl ether also has 3 carbons, but forms fewer hydrogen bonds with water due to its structure.

Which compound would be more soluble in water, ethanol or 2-pentanol? Explain.
Ethanol has 2 carbon atoms in its chain. It is more soluble than pentanol with 5 carbons.
The longer the alkyl chain, the less soluble the alcohol in water.
