I want to thank your team (Jeff) for finding a new writer when you were unable to reach my existing writer to revise my paper. I appreciate your professionalism and efforts. Thanks
The relative magnitude of the inter molecular forces are:
##CF_4 < OF_2 < CHF_3 < HF.##
All molecules will have London dispersion forces which get stronger as the molecule gets heavier (more electrons causes a shift in electron cloud distribution resulting in a temporary dipole).
##CHF_3## is a polar molecule. So it will have dipole – dipole interaction along with the weaker dispersion forces.
##OF_2## is a polar molecule with a bent shape just like ##H_2O##. There are two pairs of bonded electrons and two pairs of unbonded lone pair electrons. These lone pairs repel the bonded electrons resulting in a bent shape with an angle less than ## 105^0##. The dominant inter molecular forces would be dipole-dipole.
HF is a polar molecule. Hence the primary inter molecular forces would be dipole – dipole and hydrogen bond which is a special type of dipole – dipole interaction between the hydrogen atom and electronegative F atom.
##CF_4## has a tetrahedral structure. It is non-polar molecule. The dominant inter molecular force would be London dispersion force.
