Was this answer helpful?When you place a molecule with an electric dipole in an electric field, a force acts to turn the molecule so that the positive and negative ends line up with the field. The magnitude of the turning force is given by the formula. µ = q × d. where q is the amount of charge and d is the distance between the two charges. µ is the turning moment.

Lowest ionic character O-F, then C-F, then H-F, and finally greatest ironic character in Na-F. As a general guide, ionic character (as opposed to covalent) increases in direct proportion with the difference in electronegativity between the two bonded atoms. If the difference in electronegativity is very large, you will get a more ionic bond (e.g. a …Formal charge is used to determine which structure has the lowest energy (greatest stability). Take NOCl. O=N-Cl has formal charges of 0 on all the atoms. The structure O-N=Cl has formal charges of -1 on O and +1 on Cl. Such a structure would be super unstable (very high energy) that it won't exist.Energy required to break all four C-H bonds in methane is 1662 kJ/mol.
