Intermolecular Forces:
CH2Cl2 is both London dispersion force and dipole-dipole
BrF is polar so (dipole-dipole)
Can you explain why? How can the first one be both polar and nonpolar to have both forces.. and for BrF I thought who lacks symmetry is nonpolar
Homework Answers
London dispersion forces act due to contact area between two molecules, more is the surface contact between them, higher is the London dispersion forces,
As first molecules has sufficiently more number of atoms than BrF, so there will be London dispersion forces,
It also have dipole-diople because of polar bond between carbon and chlorine atom
BrF is having net dipole due to large difference in electronegativity so it has predominantly dipole-diople
Very less London dispersion forces but it will be
