Why the dipole moment of CH3Cl is greater than CH3F....????

DIPOLE MOMENT = CHARGE X DISTANCE

although flourine is more electronegative , but bond length of CCl is greater than that of CF.

In this case distance factor dominates over charge.[exprimental data]

Hence dipole moment of CH3Cl is higher

Dear Abhijat Pandey,

Dipole Moment = Magnitude of Charge * Distance of Seperation

Though Fluorine is more electronegative(Pauling Scal Value is 4.0) than Chlorine(Paulin's scale value is 3.0) ,the C-Cl distance is greater than C-F distance !

Hence CH₃Cl has greater dipole moment than CH₃F !

Hope you understood it now..

All the Best & Good Luck !!
