Question

Long shot, but I did a lab today and for one of the parts I had to find whether acetone or isopropyl was more volatile. I think that the person who did the trial did it wrong, so does someone know by chance? I tried looking it up online but I somehow couldn't find it

Answer 1

@Vocaloid

sorry wrong subject again.

Answer 2

I mean, based on the IMFs of Acetone and Isopropyl I would head for acetone as more volatile but my lab readings are completely different..

Answer 3

Imma go with acetone. It makes more sense

Answer 4

The higher a compound's vapor pressure, the more unstable it becomes. A lower boiling point translates into higher vapor pressure and volatility. Increasing temperature increases the pressure of the vapor, the pressure at which the gas phase is in balance with the liquid or solid phase.

Acetone Boiling point: 132.8°F (56°C)

Isopropyl alcohol/Boiling point: 180.5°F (82.5°C)

The boiling point of acetone is lower than isopropyl alcohol, so therefore acetone has a higher volatility. Great job babes xD

isopropyl alcohol can have hydrogen bond, thats why its boiling point increases.
