Even though F is more electronegative, CH3Cl has greater dipole moment because the bond length in this case is far longer than that in the case of CH3F since F is highly electronegative and it attracts the electron pair very strongly. Dipole moment is not just about charge, it is the product of charge and the bond length.

In CHCl3 i.e Chloroform there are 3 highly electronegative chlorine atoms and one hydrogen atom. due to difference in electronegativityof hand cl atoms around Carbon CHCl3 shows Dipole Moment.

Greater the value of electronegativity, higher the dipole moment. So, CHF3 is expected to have greater dipole moment. But, due to extreme smaller size of fluorine, the dipole moment of CHCl3 outerweighs that of CHF3.

because the oxygen atom is more electronegative than the fluorine atom

Why phenol has lesser dipole moment than alcohol?

As we know that dipole moment of polar molecules is greater than non-polar. In other words, in molecules where charge separation is more, it is more polar and hence having more dipole moment. In phenol, due to resonance, there is positive charge on oxygen. So there is no more charge difference between carbon of ring and oxygen of OH group. This is the reason, it has less dipole moment.


Which has more dipole moment C2H3CL or C2H5CL?

C2H5-CN ethyl cyanide has high dipole moment while C2H5-NC molecule is not possible due to incomplete valency of carbon atom.


Which molecule has polar bond but its overall dipole momen is zero?

Symmetric molecules have no dipole moment. An example is carbon tetrachloride, CCl4 , which has no dipole moment yet the C-Cl bonds are polar, (chlorine is more electronegative than carbon). The chlorine atoms each have a small negative charge but because the molecule is tetrahedral there is no dipole and therefore no dipole moment


Why o-chlorophenol has less dipole moment than o-fluorophenol?

The reason for the larger dipole moment of o-fluorophenol is because F is more electronegative than Cl.


What is the much more polar solvent?

Formamide is the most polar solvent. It has a dipole moment of 3.73 and a dielectric constant of 109. As a comparison, water has a dipole moment of 1.85 and a dielectric constant of 80. The higher the dipole moment value and the dielectric constant, the more polar the solvent. At the opposite, the less polar solvents are hexane, benzene and carbontetrachloride.


Why does CO have a dipole moment?

Yes. CO is polar. Polar molecules have dipole-dipole forces. They also have London dispersion forces, but dipole-dipole forces are stronger.


Why Nh3 and Nf3 has high dipole moment?

This is because in ammonia the direction of resultant dipole is towards lone pair and hence it has high dipole moment but in case of NF3 the direction of resultant dipole moment is opposite to the lone pair and hence the dipole moment gets less.


What is dipole moment of chloroethane?

There are multiple forms of the molecule "chlorooctane." This is because the chlorine atom can be attached to the octane chain in several different places, and each different placement will result in a different dipole moment. If you specify the structure of the compound more precisely (1-chlorooctane or 2-chlorooctane for example), it is possible to determine its dipole moment.


Net dipole moment?

A separation of charge forming a positive and a negative end of a molecule. Good luck!


Water is a polar molecule because?

Oxygen is more electronegative than hydrogen and creates a dipole moment.


Why is dipole moment of water greater than that of ammonia?

oxygen is more electronegative than nitrogen so we would expect a greater bond dipole for O-H as compared to N-H. Also water has two lone pairs whereas ammonia has only one. and these contribute to the net dipole moment.


Where does the dipole in the nitrogen-hydrogen bond point?

The dipole in the nitrogen-hydrogen bond points towards the nitrogen end. The arrow showing a dipole moment points towards the more electron rich region, with its tail at the electron poor region.
