Recap - Butanol and Ether

Part of the Structure and Bonding section of Coddy's Chemistry journey. Lesson 48 of 49.

Challenge

Butan-1-ol and ethoxyethane have the same molecular formula, C₄H₁₀O, and almost the same mass. Yet butan-1-ol boils at 118 °C and ethoxyethane at only 35 °C.

The full structural formulas of butan-1-ol, with an O-H at the end of a four-carbon chain, and of ethoxyethane, with an oxygen between two ethyl groups

Two molecules with the same formula, C4H10O

The difference lies in a functional group that lets butan-1-ol molecules hydrogen bond to each other. Mark every functional group of butan-1-ol.
