What is cyclohexane freezing point?
6.50 °C.
Exercise: The freezing point of cyclohexane is 6.50 °C.
How could you distinguish between cyclohexane and cyclohexene using IR?
It is [possible] to distinguish cyclohexane and cyclohexene by IR spectroscopy. The =C-H stretch should appear in the spectrum of [only cyclohexene] around [3000‑3100] cm-1, which will be probably easier to see than the corresponding C=C around [1600‑1680] cm-1. what are the units on an IR Spectra?

What is the vapor pressure of cyclohexane?

| T [K] | P [kPa] | State |
|---|---|---|
| 279.23 | 5.164 | Vapor-Liquid |
| 283.85 | 6.575 | Vapor-Liquid |
| 285.68 | 7.227 | Vapor-Liquid |

Why does cyclohexane have a low melting point?
This, in turn, depends on their shape. Cyclohexane has a high degree of symmetry, and this enables the molecules to pack nicely into a crystalline structure with strong London dispersion forces between them.. Thus, cyclohexene has a much lower melting point than cyclohexane (-103.5 °C vs. 6.5 °C).
What is the freezing point depression constant of T-butanol?
Problem: The freezing point of t-butanol is 25.50°C and Kf is 9.1°C • kg/mol. Usually t-butanol absorbs water on exposure to air.
What are the hazards of cyclohexane?
The following acute (short-term) health effects may occur immediately or shortly after exposure to Cyclohexane: Contact can irritate and burn the skin and eyes. Inhaling Cyclohexanecan irritate the nose and throat causing coughing and wheezing.
Why is the freezing point the same as the melting point?
The freezing point of a substance is defined as the temperature at which matter or a substance is changed from its liquid state into solid. For some substances, the melting point is equal to or the same as its freezing point. For mixtures and organic compounds, however, the freezing point is lower than the melting point.
What is the formula for freezing point?
Calculate the depression of the freezing point using the formula Tf = (i x Kf x m), where Tf is the how much the freezing point drops in degrees Celsius .
What is the flash point of cyclohexane?
CYCLOHEXANE is a clear colorless liquid with a petroleum-like odor. Used to make nylon, as a solvent, paint remover, and to make other chemicals. Flash point -4°F. Density 6.5 lb / gal (less than water) and insoluble in water. Vapors heavier than air.
