The electron-dot resonance structure, formal charge and the most important resonance structure has to be given for the molecules in Table 19.6. Also the paramagnetic molecules has to be indicated. Concept introduction: Lewis structure otherwise known as Lewis dot diagrams or electron dot structures that show the bond between atoms and lone pairs of electrons that are present in the molecule. Lewis structure represents each atom and their position in structure using the chemical symbol. Excess electrons forms the lone pair are given by pair of dots, and are located next to the atom. Formal charge = [ valence electrons ] – [ electrons in lone pairs + 1/2 the number of bonding electrons ] .

Carbon, nitrogen, and oxygen form two different polyatomic ions: cyanate ion (NCO) and fulminate ion (CNO). Write Lewis structures for each anion, including near-equivalent resonance structures (do not add any arrows between structures) and indicating formal charges. The isocyanate ion also has two near-equivalent structures, but the formal charge on the nitrogen attom cannot be reduced to zero: Cyanate ion (NCO)

Although I3- is a known ion, F3- is not. (a) Draw the Lewis structure for I3- (it is linear, not a triangle). (b) One of your classmates says that F3 - does not exist because F is too electronegative to make bonds with another atom. Give an example that proves your classmate is wrong. (c) Another classmate says F3- does not exist because it would violate the octet rule.Is this classmate possibly correct? (d) Yet another classmatesays F3- does not exist because F is too small to make bonds tomore than one atom. Is this classmate possibly correct?

The carbonate anion, CO32- , is a resonance hybrid. Draw all of the important resonance structures for this molecule. If an atom has a nonzero formal charge, be sure the formal charge is shown clearly in the structure. Use the resonance structures to calculate the average formal charge on each O atom (which are all equivalent in the "true" structure). [Note: all of the important contributing resonance structures have octets around each atom that desires an octet.]
