The 30% ethanol extract … WebWhy does 1-butanol (CH3CH2CH2CH2OH) have a lower boiling point than 1-hexanol (CH3CH2CH2CH2CH2CH2OH)? Answers Ethanol has an -OH group and only 2 carbon atoms; 1-hexanol has one -OH group for 6 carbon atoms and is thus more like a (nonpolar) hydrocarbon than ethanol.

Webdifferences in LDF’s, the vapour pressure difference must be due to weaker ‘hydrogen-bonding’ in 2-butanol. We can rationalize this by looking at the structure and recognizing that the O-H group in 2-butanol is more crowded and less accessible to neighboring molecules than the O-H group in 1-butanol. OH OH Web1-butanol is the second because of the OH group and thus, hydrogen bonding. Remember, the order of increasing intramolecular interactions in covalent compounds: Symmetry and Melting Point. Aside from the intermolecular interactions, however, the melting point depends also on how the molecules are packed or arranged in the solid form.
