Question:

12. (0.5 points) Do the atoms of oxygen and hydrogen in #12 satisfy the Rule of the Octet? How can you tell? 13. (1 point) Draw

12. (0.5 points) Do the atoms of oxygen and hydrogen in #12 satisfy the Rule of the Octet? How
can you tell?
13. (1 point) Draw a structural formula for the water molecule from #12.
14. (2 points) Refer back to the previous three molecules as examples. Complete the following
with the appropriate numbers:
An atom of hydrogen needs
electrons to fill its outermost shell, and, in all of the
molecules so far, one atom of H formed
bonds(s) to be stable.
An atom of oxygen needs electrons to fill its outermost shell, and, in all of the
molecules so far, one atom of O formed
bonds(s) to be stable.
Generalizing from these examples, I would say that the number of electrons needed to fill the
outermost shell of an atom is
the number of covalent bonds that atom
must form to build a stable molecule.
A. unrelated to
B. the same as
C. twice
D. half
If this pattern continues, an atom of nitrogen will always form bonds to be stable, an
atom of carbon will always form bonds to be stable, and an atom of sulfur will always
form bonds to be stable.
15. (1 point) The following is the molecular model of ethanol (C2H5OH):
Draw its structural formula.
