A perfect (or pure) dipole is the contrary to a 'physical' dipole. The Physical (electric) dipole consists of two equal and oppsite charges (+/-)q, separated by a finite, and well defined distance, d.
The perfect dipole is a model (or an approximation) for the physical dipole, where we say that d is ~equal to zero. This is legit when we observe the dipole (measure the electric field, E, or the potential, V) at distances, r, far greater than d, and simplifies our equations for E(r,t) and V(r,t).
A perfect dipole is an imaginary concept used in physics to represent a molecule or an object with a perfectly symmetrical charge distribution, resulting in a uniform electric dipole moment. In reality, perfect dipoles do not exist, but the concept is a useful simplification in theoretical calculations.

What electric field parallel or anti parallel to the electric dipole?
An electric field parallel to an electric dipole will exert a torque on the dipole, causing it to align with the field. An electric field anti-parallel to an electric dipole will also exert a torque on the dipole, causing it to rotate and align with the field in the opposite direction.
How does a torque affect the dipole in an electric field?
A torque applied to a dipole in an electric field causes the dipole to align itself with the direction of the field. The torque will tend to rotate the dipole until it reaches the stable equilibrium position where it is aligned with the electric field.
What is two opposite electric charges separated by a short distance called?
Two opposite electric charges separated by a short distance are called an electric dipole.
When is a dipole in unstable equilibrium in an electric field?
A dipole is in unstable equilibrium in an electric field when the external electric field opposes the natural alignment of the dipole moment. This causes the dipole to experience a torque that rotates it away from its equilibrium position. If the force pushing the dipole away from equilibrium is stronger than any restoring forces, the equilibrium is considered unstable.
How do you calculate dipole field?
The magnetic field created by a dipole can be calculated using the formula: B = (μ0 / 4π) * (2m / r^3), where B is the magnetic field strength, μ0 is the permeability of free space, m is the magnetic moment of the dipole, and r is the distance from the dipole.
In dipole-dipole forces how thermal energy causes the molecules not to have perfect alignment?
Thermal energy causes molecules to vibrate and rotate randomly, leading to constant motion. This motion disrupts the perfect alignment of the molecules in dipole-dipole forces. As the temperature increases, the kinetic energy of the molecules also increases, further preventing them from maintaining a fixed orientation.
Types of molecular attraction?
Ion-dipole, Dipole-dipole, and Dipole-induced dipole.
What kind of forces is a dipole-dipole force?
Dipole-dipole interactions are of electrostatic nature.
When would dipole-dipole forces be significant?
When molecules have permanent dipole moments
What kind of force is a dipole dipole of force?
Dipole-dipole interactions are of electrostatic nature.
Does ch3cl have dipole-dipole attractions?
Yes, CH3Cl (methane) has dipole-dipole attractions. This is because the molecule has a net dipole moment resulting from the uneven distribution of electrons around the carbon and chlorine atoms. This dipole moment allows CH3Cl to exhibit dipole-dipole interactions with other polar molecules.
Is CH2O a dipole dipole?
Yes, CH2O is a polar molecule due to the difference in electronegativity between carbon and oxygen atoms. It exhibits dipole-dipole interactions as a result of this polarity.
Which has the smallest dipole-dipole forces NO O2 HBr or CH3Cl?
O2 has the smallest dipole-dipole forces because it is nonpolar, lacking a permanent dipole moment. The other molecules listed (NO, HBr, CH3Cl) all exhibit polar bonds and have dipole moments, allowing for stronger dipole-dipole interactions.
Is ammonia a dipole dipole or extreme dipole?
Ammonia is a dipole-dipole molecule, meaning it has a positive and negative end due to differences in electronegativity between the nitrogen and hydrogen atoms, creating a dipole moment.
why HC1has dipole-dipole forces of attraction?
dipole-di[pole attraction
What is the intermolecular force for H2S?
The intermolecular force for H2S is dipole-dipole interaction. Since H2S is a polar molecule with a bent molecular geometry, it experiences dipole-dipole forces between the slightly positive hydrogen atoms and the slightly negative sulfur atom.
Is NaCl dipole-dipole?
Yes.
