Why is the Dipole moment of CH3F less than CH3Cl though it should be opposite??

since the size of  F atom is small , the bond moment of C-F   is small than the bond moment of C-Cl

because of the large size of the chlorine atom

But F is more electronegative than Cl. Also, by your answer, CH3I should have higher dipole moment than CH3Cl but this is opposite.

CH3Cl has larger dipole moment than CH3F because dipole moment is based on the product of distance and charge, and not just charge alone.

Fluorine is more electronegative than chlorine, but, the carbon-fluorine bond is also much shorter than the carbon-chlorine bond: 139 pm vs 178 pm. Thats why the dipole moment of chloromethane is higher than the dipole moment of fluoromethane.

As the size of fluorine is less compared to chlorine the bond pair electrons of carbon-fluorine bond will get repelled by the lone pair electrons of fluorine. So the dipole moment will decrease.While this ill not happen in choromethane.

							As dipole moment depend on product of charge and distance between atom . Chlorine have exceptionally  large size than fluorine  and it have more partial charge than flourine.

							CH3Cl has higher dipole moment then CH3F because dipole moment is product of charge and distance between atoms In case of F the distance is very less as compared to that of Cl

							It`s because of exceptionally small size of flourine dude take it easy it`s just an exception nothing to worry

Dear student,
Please find the answer to your question.
