What is the melting point of cyclohexanol?
What is the melting point of cyclohexanol?
78.67°F (25.93°C)
Cyclohexanol/Melting point
Why cyclohexanol has higher boiling point?
Boiling point of a compound is directly related to intermolecular force strength which means cyclohexanol is going to have a higher boiling point than cyclohexene. 2. A minimum boiling azeotrope represents a mixture of two or more liquids whose composition cannot be changed by distillation.
How is cyclohexene prepared from cyclohexanol?
Procedure: Pour cyclohexanol (10.0 g, 10.6 mL, b.p. 161°) into a 50 mL round bottom flask (small neck) and cautiously add 85% phosphoric acid (3 mL). Add 3 boiling chips and arrange for a distillation using a cooled 10 mL graduated cylinder as a receiver. (Cool the cylinder by standing it in a beaker of ice and water).
What is the melting point in OC of cyclohexene you can find the answer on Wikipedia?

Does cyclohexanol or cyclohexene have a higher boiling point?
The alkene and water distill from the reaction flask as they are formed, whereas the unchanged alcohol remains behind to be further acted on by the acid. In the present case, the dehydration is carried out at 130-140 oC, which is above the boiling point of cyclohexene (83 oC) but below that of cyclohexanol (161 oC).
Why does cyclohexane have a higher boiling point than cyclohexene?
Cyclohexene is planar, and can pack closer together which means more London Dispersion forces (van der waals(sp?) to us oldsters) holding them together making it take more energy to separate them, and by extension, a higher boiling point. Cyclohexane has all those axial hydrogens poking out.
What is the melting point of cyclohexane?

Why is cyclohexene lower boiling than cyclohexanol?
The lower boiling point present in the distillation of cyclohexanol may have been due to the weak hydrogen bonds in the alcohol functional group and water, or the weak alkene bonds. The initial amount of cyclohexanol used was 2.0 g and the finished amount of cyclohexene obtained was 0.43 g.
