When using formal charges to determine the best structure for a molecule, which of the following is NOT true? Select one of the following The best structure will place positive formal charges on the most electronegative atoms. The best structure will minimize formal charges on the atoms. The best structure will follow the octet rule if possible. The best structure will place negative formal charges on the most electronegative atoms.

Which one of these statements about formal charge is true? Formal charge is most useful for ionic compounds. Formal charge is used in calculating the dipole moment of a diatomic molecule. Formal charge is the same as oxidation number. To draw the best Lewis structure, you should minimize formal charge. Formal charge takes into account the different electronegativities of the atoms in a molecule.

Which of the following is/are true concerning formal charge? The formal charge each individual atom molecule or ion an actual atomic charge that can be experimentally determined The formal charge each individual atom always the same for each possible resonance form: The sum of the formal charges each atom molecule or ion equal the overall charge of the molecule or ion: Select one: a. 1 only b. 2 only c. 3 only d. 1 and 2 e. none
