Two electrostatic potential maps, one of methyllithium (CH3Li) and one of
chloromethane (CH3Cl) are shown. Based on their polarity patterns, which do you
think is which?
7.32
What is the geometry around the central atom in each of the following
molecular models?
7.33
What is the geometry around the central atom in each of the following
molecular models? (There may be a “hidden” atom in some cases.)
7.34
Three of the following molecular models have a tetrahedral central
atom, and one does not. Which is the odd one? (There may be a
“hidden” atom in some cases.)
7.35
Identify each of the following sets of hybrid orbitals:
7.36
The following ball-and-stick molecular model is a representation of
acetaminophen, the active ingredient in such over-the-counter headache remedies
as Tylenol (red = O, gray = C, blue = N, ivory = H):
(a) What is the molecular formula of acetaminophen?
(b) What is the geometry around each carbon and nitrogen? (The lines between
atoms indicate connections only, not whether the bonds are single, double, or
triple.)
(c) What is the hybridization of each carbon and nitrogen?
7.37
The following ball-and-stick molecular model is a representation of thalidomide, a
drug that causes birth defects when taken by expectant mothers but is valuable for
its use against leprosy. The lines indicate only the connections between atoms, not
whether the bonds are single, double, or triple (red = O, gray = C, blue = N,
ivory = H):
(a) What is the molecular formula of thalidomide?
(b) Indicate the positions of the multiple bonds in thalidomide.
(c) What is the geometry around each carbon and each nitrogen?
