If you mean a dipole which only lasts for an instant, then you have to picture the electrons of the molecule surrounding the nuclei. In a non-polar molecule the electrons are shared evenly on average, but at any one second they may be distributed so that there is a greater density at one end than another, i.e. there is a temporary dipole.
What else can I help you with?
What is the difference between instantaneous dipole and induced dipole?
Dipole-dipole is between two polar molecules, that would be polar anyway. Dipole-induced dipole is between a polar molecule and a non-polar molecule that is now polar due to the proximity of a polar molecule.
Why a dipole develops in a molecule?
A dipole develops in a molecule when there is an unequal distribution of electron density, causing one end of the molecule to be more negatively charged and the other end to be more positively charged. This occurs due to differences in electronegativity between atoms within the molecule, leading to a separation of charge and the formation of a dipole moment.
What are the conditions for ammonia molecule to be IR active?
An IR Active stretch simply means that the vibrations of the molecule result in an overall dipole of the molecule. If a stretch has a dipole, it is IR active. If a stretch does not have a dipole. then it is IR Inactive.
Is SO2 dipole in nature?
Yes, sulfur dioxide (SO2) is a polar molecule and has a dipole moment. This is because of the difference in electronegativity between the sulfur and oxygen atoms, causing an unequal distribution of electron density within the molecule.
What is the direction of the dipole moment expected for hydrogen bromide?
The HBr molecule is linear (obviously, since it contains only two atoms). The dipole moment is a vector, parallel to the bond, pointing toward the partially positively charged atom, which is, in this case, the hydrogen. The magnitude of the dipole moment is the difference in the partial electrical charges on each atom times the spatial separation of the atoms in the bond. In a molcule with more than two atoms (more than one bond), the dipole moment of each bond must be added vectorially and the resultant vector will determine the dipole moment of the molecule. For instance, carbon dioxide has two carbon-oxygen double bonds of high polarity, but because the molecule is linear, and the individual dipoles oppose each other, the carbon dioxide molecule has no net dipole moment.
What is the difference between instantaneous dipole and induced dipole?
Dipole-dipole is between two polar molecules, that would be polar anyway. Dipole-induced dipole is between a polar molecule and a non-polar molecule that is now polar due to the proximity of a polar molecule.
How can molecule have an instantaneous dipole?
If you mean a dipole which only lasts for an instant, then you have to picture the electrons of the molecule surrounding the nuclei. In a non-polar molecule the electrons are shared evenly on average, but at any one second they may be distributed so that there is a greater density at one end than another, i.e. there is a temporary dipole.
Which comes first in London dispersion Instantaneous dipole or induced dipole?
instantaneus
Is O2 a dipole-dipole molecule?
Yes, O2 is not a dipole-dipole molecule because it is a diatomic molecule with a nonpolar covalent bond.
Is NOCl a polar or nonpolar Molecule?
A ball-and-stick model for NOCl is given below:This is a polar molecular compound. Therefore, the intermolecular forces include dipole-dipole forces and dispersion forces.Dispersion forces are also called London forces, induced dipole-induced dipole forces, or instantaneous dipole-induced dipole forces.

What is instantaneous dipole forces for nonpolar molecules?
That is dispersion force.
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.
Does a dipole moment exist with Neon?
Neon exists as a monoatomic molecule. Hence it doesn't have any permanent dipole moment. However instantaneous dipoles are present, and these give rise to London dispersion forces
Is water a dipole-dipole molecule?
Yes, water is a dipole-dipole molecule because it has a polar covalent bond between the oxygen and hydrogen atoms, creating a partial positive and partial negative charge within the molecule.
What type of molecule has Dipole-Dipole forces created?
Ay molecule with a net dipole moment will have dipole -dipole interactions. These are molecules with polar bonds caused by a diference in electronegativity between the atoms being bonded.
Is PF5 dipole-dipole?
No, PF5 is not a dipole-dipole molecule. It has a trigonal bipyramidal geometry with fluorine atoms arranged symmetrically around the central phosphorus atom, resulting in a nonpolar molecule.
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.
