You turn an electric dipole end for end in a uniform electric field.How does the work you do depend on the initial orientation of the dipole with respect to the field?
The work done by you to turn the electric dipole end for end in a uniform electric field depends on the initial orientation of the dipole with respect to the field. If the dipole is initially oriented such that its positive and negative charges are parallel to the electric field, then no net work is done as the electric field does not do any work on the dipole as the electric field lines do not transfer any energy. On the other hand, if the dipole is initially oriented such that its positive and negative charges are perpendicular to the electric field, then work is done by you to turn the dipole as the electric field exerts a force on the charges in the dipole in opposite directions, causing them to move in opposite directions. As a result, you have to do work to move the charges and turn the dipole.
What is the Dipole-dipole force?
a hydrogen bond
What is the angle between the electric dipole moment and the electric field strength due to it on axial line?
direction-along the axis of dipole from -q to +q.
What is the definition of a dipole moment?
A dipole moment is a mathematical product of the magnitude of a charge and the distance of the separation between charges. There are also many other types of dipole moments, such as transition, molecular, bond and electron.

Explain how a water molecule can be attracted to both a positive ion and a negative ion when dissolving an ionic compound?
The shape and charge distribution in a water molecule cause it to have a permanent dipole moment, which consist of a positive electric charge and a negative charge separated by a distance in space. Therefore, the part of a water molecule that corresponds to the negative charge of its dipole moment is attracted to positive ions, and the part of a water molecule that corresponds to the positive charge of its dipole moment is attracted to negative ions.
What has a positive charge at one end and a negative charge at the other end?
A polar bond occur when electrons are shared unequally. However, POLAR MOLECULES are the ones that have a slight postitive charge on one end and a slight negative charge on the other end.
What is the term for the overall direction of partial negative charge in a molecule having one or more dipoles?
Net dipole
Why does a dipole moment orient from negative to positive if in an electric field the field runs from positive to negative?
Because opposite charges attract. The negative end of the dipole moment is trying to get to the positive end of the field, and the positive end of the dipole is trying to get to the negative end of the field.
Why dipole moment is avector?
Since there is charge separation in a polar covalent bond, there is also resultant electric field from partial positive charge to partial negative charge.hence due to electric field in one direction and also magnitude of equal and opposite charge.....it is a vector.
Net dipole moment?
A separation of charge forming a positive and a negative end of a molecule. Good luck!
What do you mean by Dipole Moment and Induced Dipole Moment?
Induced dipole forces result when an ion or a dipole induces a dipole in an atom or a molecule with no dipole. These are weak forces. An ion-induced dipole attraction is a weak attraction that results when the approach of an ion induces a dipole in an atom or in a nonpolar molecule by disturbing the arrangement of electrons in the nonpolar species. A dipole-induced dipole attraction is a weak attraction that results when a polar molecule induces a dipole in an atom or in a nonpolar molecule by disturbing the arrangement of electrons in the nonpolar species.
What is molecular dipole moment?
The molecular dipole moment is a measure of the separation of positive and negative charges within a molecule. It is a vector quantity that indicates the overall polarity of a molecule. It is determined by the individual dipole moments of the bonds within the molecule and their spatial arrangement.
Application of dipole moment?
A dipole moment is defined as the mathematical product of the separation of the ends of a dipole and the magnitude of the charges. Dipole moments are created by the separation of charge over a molecule. Some common molecules with dipoles are H2O, HF, NH3, etc...
What is significance of dipole moment?
Dipole moment is the measure polarity of a polar covalent bond .In language of physics it can be defined as the measure of strength of electric dipole. It is defined as the product magnitude of charge on the atoms and the distance between the two bonded atoms. Its common unit is debye and SI unit is coulomb metre.The magnitude of dipole moment is equal to the product of either charge and the distance between the charges and its direction is from -q to +q.It is directed from the (-)ve charge to the (+)ve charge.In fact, it is the behavior of a dipole.A separation of charge forming a positive and a negative end of a molecule ~APEX
Why is HCN is a dipole-dipole compound?
HCN is a linear molecule and as nitrogen is the most electronegative atom a small negative charge builds on the nitrogen atom and a small positive charge on the hydrogen. This forms a dipole (dipole means two oppositely charged ends). The intermolecular forces between HCN molecules are electrostatic and are caused by the dipole on one molecule interacting with one on another molecule. This is called dipole -dipole interaction.
Why does hydrochloric acid though a covalent compound ionize?
HCl is strictly speaking - a polar covalent molecule with a partial positive charge on hydrogen and a partial negative charge on chlorine. When this is dissolved in water, water too being a polar molecule with a partial positive charge on hydrogen and a partial negative charge on oxygen, hydrogens of HCl are surrounded by oxygens of water forming dipole dipole bonds. So also the chlorines are surrounded by hydrogens of water. When the dipole-dipole bonds are formed, the original bond between H and Cl weakens and ultimately breaks leading to ionization.
