What is the enthalpy of combustion of octanol?

What is the enthalpy of combustion of octanol?

−5294 kJ
Octanol (C8H17OH) ( C 8 H 17 O H ) is an organic alcohol, which is a derivative of the eight carbon hydrocarbon octane. When burned in air, octanol has an enthalpy of combustion of −5294 kJ − 5294 k J .

How many isomers are there of hexanol?

If once again we employ our “chemical scissors” to cut a unique C-H bond in n-hexane, structure 1, and insert a divalent oxygen at the point of scission, we will have formed three constitutionally isomeric hexanols: 1-hexanol (6), 2-hexanol (7) and 3-hexanol (8).

How many isomers does 1-hexanol have?

Two
This colorless liquid is slightly soluble in water, but miscible with ether and ethanol. Two additional straight chain isomers of 1-hexanol exist, 2-hexanol and 3-hexanol, both of which differ by the location of the hydroxyl group.

Why does 1-hexanol have a higher boiling point than 3-hexanol?

Because it takes more force to break the inter-molecular bonds between hexanol molecules than between water molecules. Rule number 1 for boiling points is that compounds with larger molecules have higher ones.

Why does hexanol have a higher boiling point than hexane?

3-hexanone has a much higher boiling point than hexane. And that’s because dipole-dipole interactions, right, are a stronger intermolecular force compared to London dispersion forces.
