Polarity occurs when an atom of a chemical bonds to the electrons rather than the other atoms. F2 polarity occurs when the atoms in the bond are the same.
F2 has a linear shape.
f2
if molecular shape is symmatrical then its non-polar but if it is non symmatrical then its polar.
The molecular geometry of a compound helps to determine polarity because, it indicates the number of lone pairs on a central atom thus giving it specified angles and polarity (only if there are lone pairs because if there are no lone pairs on the central atom, them it is non-polar).
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.
Explain the effect of molecular polarity on behaviour.
