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 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.
Can you have a temporary dipole and a permanent dipole at the same time or TDID and PDD at the same time?
A temporary dipole occurs when through a cloud type formation, randomly electrons gather at one location. A permanent dipole is when one atom attracts more electrons effectively giving it a negative charge. Both conditions can exist at the same time.
What is the strongest intermolecular force present in HCN?
Van der Waals (a.k.a. London Dispersion Forces) and Dipole-Dipole interactions. HCN does not hydrogen bond to itself.
Why does dispersion happen?
Dispersion forces are forces that are due to certain distortions in the electron density around atoms or moleculed. They can be mainly categorized in to : 1.Induced dipole-induced dipole forces 2.Dipole dipole force 3.Induced dipole-dipole forces 4.London force Dipole forces are forces between molecules that have permanent dipole character like NaCl.However, in cases like certain molecules that do not have dipole character, there may be instantaneous distotions which leads to london forces.Dipoles can induce dipole character by thickening densities of electrons around certain atoms, leading to induced dipole interactions.
What is an covalent bond where the electrons are unequally pulled towards a certain ion is called?
I think you are referring to a "dipole". In most covalent bonds, the electrons that form the bond are not equally shared by the two atoms involved, but are -- as you say -- preferentially pulled towards one atom or the other. This results in a slightly higher electron density around one atom and slightly lower electron density around the other called a dipole. But note: atoms in covalent bonds are not called "ions". They are still referred to as atoms.

Why a dipole develops in a molecule?
a dipole develops in a molecule due to unequal sharing of electrons.
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.
BrF3 dominant intermolecular force?
BrF is polar, its dipole moment is known, 1.4D . Dipole -dipole will be the strongest intermolecular force. Dispersion forces will also be present. The argument runs - Dispersion forces are caused by the total number of electrons, compare BrF (number of electrons 44 with noble gases say Xenon, 54 electrons) BrF decomposes around 200C , its boiling point which is considerably higher than the bp of xenon (-108 oC). Indicating factors other than disperison forces are at play causing the bp to be so high.
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.
Why is ph3 Dispersion and Dipole-Dipole?
PH3 has a dipole moment , of 0.58 D. Therefore there will be dipole dipole interactions. All molecules experience London dispersion forces as these are caused by the interaction of instantaneous dipoles due to the movement of electrons within the molecules.
Can you have a temporary dipole and a permanent dipole at the same time or TDID and PDD at the same time?
A temporary dipole occurs when through a cloud type formation, randomly electrons gather at one location. A permanent dipole is when one atom attracts more electrons effectively giving it a negative charge. Both conditions can exist at the same time.
Is nitrogen hydrogen an ionic or covalent bond?
Nitrogen exists as a diatomic molecule, meaning that there are two nitrogen atoms bonded with each other. Since they are both the same element, their electronegativities are the same, the electrons are shared equally between the two atoms, which means they form nonpolar covalent bonds.
How can a 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.
