dipole moment of water is 1.85 Debye

Trichloromethane (chloroform) has a higher dipole moment compared to dichloromethane. This is because trichloromethane has more chloro groups, resulting in a more polar molecule with a stronger dipole moment.

Pyridine has a dipole moment of about 2.20 Debye due to the asymmetry of the molecule caused by the nitrogen atom's lone pair of electrons. This dipole moment allows pyridine to interact with other polar molecules through dipole-dipole interactions.
