A separation of charge forming a positive and a negative end of a molecule -- Apex
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.
No. H2 does not have a permanent dipole moment.
Yes there is a nonzero dipole moment since it is a square pyramid (molecular geometry) and has a lone pair.
Typically one where bond dipoles do not cancel due to the molecular symmetry. The lone pairs also give rise to a small dipole moment and these may cancel out small bond dipoles it depends on the relative directions of the dipole moments.
NH3 is not symmetrical.So it has a dipole moment
NH3 is an asymmetrical compound.So it is exhibits.

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.
a separation of charge forming a positive and negat2ive end of molecule
A dipole moment is defined as a measure of the molecular polarity of a compound; the magnitude of the partial charges on the ends of a molecule times the distance between them (in meters). In order for there to be a dipole moment the element must must have molecular polarity which results from molecules with a net imbalance of charge (often a result of differences in electronegativity). If the molecule has more than two atoms, both shape and bond polarity determines the molecular polarity. In general look for a difference in electronegativity of the elements of a molecule which results in polarity and thus a possible dipole moment. Note that molecular shape influence polarity so molecules with the same elements but a different shape (and vice versa) won't have the same dipole moment.
Ion-dipole, Dipole-dipole, and Dipole-induced dipole.
Typically one where bond dipoles do not cancel due to the molecular symmetry. The lone pairs also give rise to a small dipole moment and these may cancel out small bond dipoles it depends on the relative directions of the dipole moments.
NH3 is not symmetrical.So it has a dipole moment
NH3 is an asymmetrical compound.So it is exhibits.
Generally if a molecule contains polar bonds and the bond dipole moments do not cancel each other out then that molecule will have an overall dipole moment. Bond dipoles arise when there is a significant difference in electronegativity between the atoms in the bond. There some cases such as phosphine PH3 where the lone pair can make a significant contribution to the molecular dipole moment.
