Concept explainers
(a)
Interpretation:
The group number of the nitrogen should be determined according to the periodic table and whether the group number is matched with the number of dots on nitrogen in Figure 2.1 should be checked.
Concept Introduction :
In the periodic table, elements are arranged in order of increasing
Nitrogen present in the fifth column and the second period of the periodic table.
(b)
Interpretation:
The number of line bonds that are attached to
Concept Introduction :
A number of line bonds indicate the number of line bonds to the atom in the Lewis structure.
(c)
Interpretation:
Number of nonbonded electrons drawn on
Concept Introduction :
The number of nonbonded electrons are free electrons that can be seen on the atom in the Lewis structure. These are shown by using dots on the atom.
(d)
Interpretation:
The formal charge of each atom in
Concept Introduction :
Formal Charge = Group Number − Number of lines − Number of dots
Group Number refers to the column number on the periodic table.
The number of lines indicates the number of line bonds to the atom in the Lewis structure or it shows the number of bonded pairs of electrons.
Number of dots represent the number of non-bonded electrons on an atom in the Lewis structure

- Draw the Lewis structures (with formal charges) of each of the species in the indicated pair and use the lewis stucture to answer which has the longer bond? and which has the stronger bond? 1.) O2 or O2^2+ 2.) NO- or NO^3- 3.) F2 or F2^2+ 4. NO2+ or NO2^3- 5.) OF2 or FO+arrow_forward2. 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).
