Answer:
Structure “a” is a major contributor. All of the atoms have
complete valences and in addition, all of the atoms have a
formal charge of zero (All of the atoms are meeting their LDD
bonding pattern).
0 / 0 pts
Question 15
Your Answer:
Describe how individual resonance structures impact the true structure of
a molecule or polyatomic ion.
There is only one true structure. But charges are distributed to other
resonance structures, and the electron pair is always moving.
Answer:
Each contributing individual resonance structure contributes
characteristics to the overall hybrid structure of the
compound. The hybrid “averages” bond lengths and formal
charges by delocalizing them among atoms that share them in
each contributing individual resonance structure.

On a piece of scrap paper, draw the resonance structure “b” that would
result from redistributing the electrons as shown on structure “a” in the

Your Answer:
Describe the shapes associated with the atomic orbitals associated with
the main elements of organic chemistry.
S waves are spherical and P waves are shaped similar to dumbbells. The
S and P waves. The S and P waves are the two orbitals most likely to
bond.
Answer:
S orbitals are spherical (single lobe), while P orbitals are
dumbbell-shaped (two lobes).

Your Answer:
The orbital is where there is a >90% chance of electrons forming a bond.
Bonds are formed between atoms when their individual atomic orbitals
overlap.
Answer:
Atoms form bonds by overlapping individual
atomic orbitals
from
each atom to produce
molecular (bonding) orbitals.
0 / 0 pts
Question 19
Your Answer:
Explain the two types of atomic orbital overlap that contribute to bond
formation in organic molecules.
End on overlap creates sigma bonds are formed by end-on overlap of
atomic orbitals of the S orbit.
Sideways overlap, is associated with p-orbitals. They are formed when
two p-orbitals overlap and bond in a pi orbital.
Answer:
End-on overlap of atomic orbitals leads to the formation of
sigma (single) covalent bonds. Sideways overlap of P orbitals
leads to the formation of pi (multiple) covalent bonds.

What is the main difference between a qualitative analysis and a quantitative
analysis of a solution?
The two must be done independently of each other, as they are completely
unlike.
A qualitative analysis must always be done before a quantitative analysis.
A quantitative analysis must always be done before a qualitative analysis.
A qualitative analysis identifies the type of ion in solution and the quantitative
analysis will determine how much of this ion is present.
A quantitative analysis identifies the type of ion in solution and the qualitative
analysis will determine how much of this ion is present.

What will be the conclusion of the test if no precipitate forms? Lead(II) ions are not present in solution. Lead(II) ions are present in the solution. Lead(II) ions are present, but in a very small concentration. More sodium nitrate solution needs to be added before a conclusion can be made.
