Gas chromatography and retention time - Chemistry Stack …

5/1/2018· As for the boiling points, the highest boiling point belongs to octane,then propanol and the lowest boiling point is for butanone. I know that the lower the boiling point is, the higher the vapor pressure of the compound and the shorter retention time usually is because the compound will spent more time in the gas phase.

Comparison of boiling points of Butanoic acid - StuDocu

Reduce the compounds boiling point as shown in table 1. butanic acid and 2-methylpropoic acid are both very similar but 2-methylpropic has a lower boiling point. This is because the methyl group reduces the strength of the molecular bonds in its carbon chain and creates a Van der waals reactions which is the weakest form of a molecular bond.
