(a) CH3F has a polar C–F bond whereas all the bonds in CH4 are of low polarity. CH3F has dipole-dipole and London force intermolecular attractions whereas CH4 has only London force attractions. Therefore CH4 has a lower boiling point than CH3F. This accounts for the high boiling points of these compounds.Click to see full answer. Regarding this, does ch4 have a higher boiling point than CH3Cl?The order of the distillates would be CH4, CH3Cl, CH2Cl2, CHCl3, and CCl4. Cl is larger than H and allows greater van der Waals contact. Water has the highest boiling point because it has the greatest degree of hydrogen bonding and is the most polar, allowing for high intermolecular force levels. which molecule has a higher boiling point? Alkanes – Straight Chain Versus Branched The more the molecules can touch each other, the more London dispersion forces there are, and the higher the boiling point. For example, pentane has a boiling point of 36.1 C, while 2,2-dimethylpropane has a boiling point of 9.5 C. Also to know, why does ch3i have a higher boiling point than ch3f? I thought, since Cl is more electronegative, it withdraws more electron density to its part and hence increase dipole movement within the atom and hence, requiring more energy to split them up and that implies higher boiling point for CH3Cl.Why does HI have a higher boiling point?| Socratic ) Hence the boiling point of HI is highest because of it’s big molecular size (the intermolecular van der Waals forces would be strongest between the large sized molecules in comparison to smaller ones- van der Waals forces ).
