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 else can I help you with?
If a molecule contains polar bonds the molecule may or may not be polar overall?
A molecule with polar bonds may or may not be polar overall, depending on its shape and symmetry. If the polar bonds are arranged symmetrically, their dipole moments can cancel each other out, resulting in a nonpolar molecule. Conversely, if the arrangement is asymmetrical, the dipole moments do not cancel, leading to an overall polar molecule. Thus, both the presence of polar bonds and the molecular geometry are crucial in determining the molecule's polarity.
How is geometrical symmetry related to the polarity of a molecule?
Geometrical symmetry influences the overall polarity of a molecule. A symmetrical molecule typically has no overall dipole moment, making it nonpolar, while an asymmetrical molecule will have a dipole moment, making it polar. This polarity affects the molecule's interactions with other molecules and its physical properties.
When a polar molecule attracts the electron in a non polar molecule what happens?
a dipole in induced.
Is CH3F polar or non polar?
This compound, called propane, is nonpolar.
Is polar bond always polar molecule?
no not really if they dont have an acute bond angle between them or have a 180 degree bond angle with the polarities running in opposite direction the overall molecule will not have a dipole.
Does a polar molecule have a net dipole moment?
Yes, a polar molecule has a net dipole moment because it has a separation of charges, creating a partial positive and a partial negative end within the molecule. This results in an overall dipole moment, making the molecule polar.
If a molecule contains polar bonds the molecule may or may not be polar overall?
A molecule with polar bonds may or may not be polar overall, depending on its shape and symmetry. If the polar bonds are arranged symmetrically, their dipole moments can cancel each other out, resulting in a nonpolar molecule. Conversely, if the arrangement is asymmetrical, the dipole moments do not cancel, leading to an overall polar molecule. Thus, both the presence of polar bonds and the molecular geometry are crucial in determining the molecule's polarity.
What molecule has an overall dipole moment?
All polar molecules have a permanent dipole moment, but London dispersion forces in non-polar molecules can cause temporary dipole moments as well.
Is a dipole-dipole interaction more likely to occur in a polar or nonpolar molecule?
A dipole-dipole interaction is more likely to occur in a polar molecule rather than a nonpolar molecule.
How is geometrical symmetry related to the polarity of a molecule?
Geometrical symmetry influences the overall polarity of a molecule. A symmetrical molecule typically has no overall dipole moment, making it nonpolar, while an asymmetrical molecule will have a dipole moment, making it polar.

What is the dipole moment of methanol and how does it contribute to the molecule's overall polarity?
The dipole moment of methanol is 1.70 D. This means that methanol has a significant separation of positive and negative charges within the molecule, making it polar. The dipole moment contributes to the overall polarity of methanol, making it capable of forming hydrogen bonds and interacting with other polar molecules.
Is CH3F polar or non polar?
This compound, called propane, is nonpolar.
What is the dipole moment of CH2Cl2 and how does it contribute to the molecule's overall polarity?
The dipole moment of CH2Cl2 is 1.60 D. This means that the molecule has a significant separation of charge, with the chlorine atoms pulling electron density towards themselves. This creates a polar molecule, as the overall dipole moment does not cancel out due to the asymmetrical arrangement of the atoms.
What are examples of dipole induced dipole forces?
Examples of dipole-induced dipole forces include the interaction between a polar molecule (with a permanent dipole moment) and a nonpolar molecule (with an induced dipole moment) or the interaction between a polar molecule and a nonpolar atom. This type of interaction leads to a temporary polarization in the nonpolar molecule or atom due to the presence of the polar molecule, resulting in a weak attractive force between them.
What will a molecule in which the polar covalent bonds do not cancel out be?
A molecule with polar covalent bonds that do not cancel out will be polar overall. This is because the bond dipoles do not cancel each other out, leading to an overall molecular dipole moment. Examples of such molecules include water (H2O) and ammonia (NH3).
Is polar bond always polar molecule?
no not really if they dont have an acute bond angle between them or have a 180 degree bond angle with the polarities running in opposite direction the overall molecule will not have a dipole.
