Two of these molecules / polyatomic ions cannot be adequately
described using a single Lewis structure. Check the two formulas
that must be written as a combination of resonance structures.
Check all that apply:
A) HCN
B) OF2
C) NH4
D) O3
E) H2CO
F) NO3^-
Draw the complete Lewis structure (including lone pairs of
electrons) for the anion that is formed after acetic acid has lost
its acidic hydrogen. Can you draw more than one structure? What do
you call it when more than one Lewis Structure is possible for an
ion or a molecule
fill out the information below for the polyatomic anion in the
formula unit M2SeO3 where M represents an alkali metal.
A. Number of valence electrons
B. Lewis Structure
C. 3D Sketch
D. Electron geometry
E. Molecular geometry
F. Hybridization
G. Overall polarity (nonpolar or polar)
Identify the following as Lewis acids or bases. For a polyatomic
molecule, you should be concerned with the central atom, e.g., the
nitrogen in NH3
b. Co2+
d. N(CH3)3
e. BBr3
f. AlCl3
g. K+
h. Ca2+
i. Hg2 2+
