Chloromethane has a larger dipole moment than trichloromethane. Does that mean that the hydrogen bond (C-H...O type) between chloromethane and acetone is stronger than that of trichloromethane and acetone?

  • $\begingroup$ It has nothing to do with dipole moment of molecule, but of the C-H bond. In chloroform it's more polarised, so bond has about 2 kJ per mole. With chloromethane h-bond would be much weaker. $\endgroup$

  • $\begingroup$ @Mithoron Why chloroform is more polarised than chloromethane? According to this, chloromethane has a larger dipole moment, does it mean it is more polarised? $\endgroup$
