Concept explainers
(a)
Interpretation:Whether there is any box in the table in model 5 having N atom with zero bonds and 3 lone pairs.
Concept introduction:Losing 1 electron around an atom from its ground state gives a +1 formal charge to that atom. Adding extra electron to an atom will give a negative charge to the atom.
(b)
Interpretation: Whether there is any box in the table in model 5 having O atom with 3 bonds and zero lone pairs.
Concept introduction: Losing 1 electron around an atom from its ground state gives a +1 formal charge to that atom. Adding extra electron to an atom will give a negative charge to the atom.
(c)
Interpretation: The reasons for the statement being true should be explained.
Concept introduction: Losing 1 electron around an atom from its ground state gives a +1 formal charge to that atom. Adding extra electron to an atom will give a negative charge to the atom. The occurrence of formal charges can be determined by counting the number of bonds & lone pair.

In biologically relevant molecules, carbon and the halogens don't have a charge. In contrast, nitrogen (neutral or positively charged) and oxygen (neutral or negatively charged) don't always appear in their uncharged form. Consider the following questions. a. Add any unshared pairs of electrons necessary to complete the Lewis structure shown for formaldehyde (note: there are no formal charges in this molecule). b. Assign any formal charges necessary to complete the structure shown for the acetylide anion. c. Recalling that atoms want a complete octet, add unshared pairs of electrons, and assign formal charges as appropriate to the Lewis structure of the amino acid aspartic acid as it would exist at a physiological pH of ~7.4 (aspartic acid has an overall -1 charge at this pH).
