Draw the structure of butanol and show water molecules in hydrogen bonds to the butanol. How many should there be? remember the H bonding rules. O atoms H bond (each can participate in 2 H bonds) and H atoms covalently attached to O atoms can H bond. IMPORTANT: H bonds are indicated by dashed lines, not solid lines. See the text - in the section on alcohol properties and water solubilities for H bond diagrams and information.
