The premise of the question is "if you put two separate liquid spots from water and octane, octane evaporates faster", which sounds like equal volume (as opposed to equal mass or equal moles), | |

There are indeed many isomers of octane. 2,2,4-trimethylpentane does have a boiling point of 99C, lower than water (while some other isomers, particularly n-octane, have a lot higher boiling point.) We should be sure we are comparing the same substance. Also, the per-mass latent heat of octane is indeed much lower than water. (They have similar per-mol latent heat, but the molecular weight of octane is much higher. ) | |
