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.
What else can I help you with?
Is carbon tetrachloride or chloroform more polar?
Chloroform is more polar than carbon tetrachloride. This is because chloroform has a dipole moment due to the electronegativity difference between carbon and chlorine atoms, while carbon tetrachloride is nonpolar as the four chlorine atoms cancel out any dipole moments.
Dipole moment of dichloromethane is high or trichloromethane?
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.
Does CH3NH2 have a dipole moment?
Yes, CH3NH2 (methylamine) has a dipole moment because the molecule is polar. The nitrogen atom is more electronegative than the carbon and hydrogen atoms, leading to an unequal sharing of electrons and the presence of a net dipole moment in the molecule.
Why chcl3 is more acidic than chf3?
So the idea behind determining which compound is more acidic is linked to the stability of the conjugate bases. The more stable the conjugate base, the easier it is for the compound to lose a proton, the more acidic the compound. Comparing the two conjugate bases, CF3- and CCl3-. The negative charge on CF3- is stabilised by the induction effect of the electronegative fluorine while the negative charge on CCl3- is stabilised by both induction effects of chlorine and by delocalisation. This delocation can happen in CCl3- because the filled 2p orbitals of C can overlap with the empty 3d orbitals of Cl which lowers the energy. Some people call this backbonding. However F does not have empty d orbitals and this overlap cannot occur. Therefore, although the induction effect of F is stronger, the combination of induction and back bonding effect better stabilises the conjugate base in CHCl3, making it a stronger acid.
Does NI3 have a dipole moment?
Yes, NI3 has a dipole moment because it is a polar molecule. The nitrogen atom is more electronegative than the iodine atoms, resulting in an uneven distribution of charge and creating a dipole moment.

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.

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.
Is there a dipole moment in IF5?
Yes, IF5 has a dipole moment because fluorine is more electronegative than iodine, causing an uneven distribution of electron density in the molecule. This creates a separation of charge, resulting in a net 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.
What is the relationship between dipole moment and polarizability in molecules?
The dipole moment of a molecule is related to its polarizability. A molecule with a higher dipole moment tends to have higher polarizability, meaning it can be easily distorted by an external electric field. This is because the distribution of charge within the molecule is more uneven in molecules with higher dipole moments.
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
What is direction of the arrow representing the dipole moment of the molecule BrF?
The direction of the arrow representing the dipole moment of the molecule BrF would point towards the more electronegative atom, which in this case is the fluorine (F) atom. This is because fluorine is more electronegative than bromine (Br), causing an uneven distribution of electron density within the molecule, resulting in a dipole moment pointing towards the fluorine atom.
Why o-chlorophenol has less dipole moment than o-fluorophenol?
The dipole moment of a molecule is determined by the difference in electronegativity between the atoms in the molecule. Fluorine is more electronegative than chlorine. Thus, o-fluorophenol, with a highly electronegative fluorine atom, will have a larger dipole moment compared to o-chlorophenol, which has a less electronegative chlorine atom.
