About This Document

The boiling point is the Minimum Temperature of any substance at which the liquid phase of the substance turns into the Gaseous Phase. The boiling point is considered to be an imperative aspect to measure the strength of forces present between the molecules. The three main aspects which affect the boiling point of any substance are as highlighted below (Ashenhurs, 2011): Presence of branching in substance reduces the boiling point High number of carbon molecules increases the boiling point Strength of intermolecular forces.

Introduction Boiling point is the minimum temperature of any substance at which the liquid phase of thesubstance turns into gaseous phase. Boiling point is considered to be an imperative aspect inorder to measure the strength of forces present between the molecules (Stone, 2013).The three main aspects which affect the boiling point of any substance are as highlighted below(Ashenhurs, 2011):Presence of branching in substance reduces the boiling pointHigh number of carbon molecules increases the boiling point Strengthofintermolecularforces(Hydrogenbonding>Dipoledipoleforce>Londondispersionforce)Intermolecular forces are the forces which are working between the molecules of the compoundand bind them together. These forces are London dispersion, hydrogen bonding and dipole-dipole force and so forth. The boiling point of 1-pentanol and 2- pentanone are as given below (Kelter, Mosher and Scott,2008):CompoundChemical FormulaBoiling PointInter molecule forces1-pentanolC5H12O138 oCHydrogen bondingDipole-dipoleinteractionLondon dispersioninteraction2- pentanoneC5H10 O101 oCDipole-dipoleinteractionLondon dispersioninteraction1
