Expert Answer

Step 1

The true statements about formal charge are to be selected:

  1. Formal charge is the same as oxidation number.
  2. To draw the best Lewis structure, you should minimize formal
  3. Formal charge takes into account the different electronegativities of the atoms in a molecule.
  4. Formal charge is most useful for ionic compounds.
  5. Formal charge is used in calculating the dipole moment of a diatomic
Step 2

Formal charge is the actual charge on the atom in a molecule assuming that in a chemical bond electrons are equally shared between the two atoms.

It helps in identifying the most stable resonance structure as the stable structure has the least formal charge.

It is calc...
