The boiling point of n-hexane is given as 69oC.

n-hexane is also a structural isomer of hexane. The above image shows the 5 structural isomers of hexane. n-Hexane: The boiling point of n-hexane is higher than that of other hexane compounds. Hexane is an unbranched hydrocarbon with formula C 6 H 14. Therefore, it does not dissolve in water or in any other polar solvent. “Hexane isomers” By Steffen 962 – Own work, Public Domain) via Commons Wikimedia 2.
