Formal charge structures

It is absolutely critical to draw these formal charges. Structures drawn without them are wrong. In fact, if you forget to draw the formal charges, then you are missing the whole point of resonance. Let s see why. Look at the resonance structure we just... [Pg.29]

Structures and are equivalent and make identical contributions to the resonance hybrid. Because of their formal charges, structures G, . and make lesser contributions. Overall, this compound has considerable resonance stabilization. [Pg.93]

Stracture I obeys the octet rule but has nonzero formal charges. Structure II has an expanded valence shell with zero formal charges. According to formal charge rules, structure II is the more important form. [Pg.312]

Abnormals have no all-neutral formal charge structure in the free carbene (4.19,4.21 and 4.23 deprotonated at ring position 3). [Pg.479]

Like nitric acid each of the following inorganic compounds will be frequently encountered in this text Calculate the formal charge on each of the atoms in the Lewis structures given... [Pg.19]

Formal charges are based on Lewis structures m which electrons are considered to be shared equally between covalently bonded atoms Actually polarization of N—H bonds m ammonium ion and of B—H bonds m borohydride leads to some transfer of positive and negative charge respectively to the hydrogens... [Pg.19]

None of the atoms in the Lewis structure shown in step 6 possesses a formal charge An alternative Lewis structure for methyl nitrite... [Pg.20]

Among structural formulas in which the octet rule IS satisfied for all atoms and one or more of these atoms bears a formal charge the most stable reso nance form is the one in which negative charge re sides on the most electronegative atom... [Pg.26]

Each contributing Lewis structure must have the same number of electrons and the same net charge although the formal charges of individual atoms may vary among the various Lewis struc tures... [Pg.27]

Electron Delocalization in the Conjugate Base With a of —1 4 nitnc acid is almost completely ionized m water If we look at the Lewis structure of nitric acid m light of what we have said about inductive effects we can see why The N atom m nitric acid IS not only electronegative m its own right but bears a formal charge of +1 which enhances its ability to attract electrons away from the —OH group... [Pg.42]
