Homework directions: Read/review 4.2 and 4.3 in Neil 9e,
then create a diagram of the following make-believe
molecule (make it large; I would turn my journal page
sideways!):

Ten C’s long, in a straight chain

Put a double bond between C5 and C6; use single
bonds between the other C’s

Show the H’s on C5 and C6 in “cis” arrangement

Put an amino group on C1

Put a hydroxyl group on C2

Put a sulfhydryl group on C3

Put a methyl group on C7

Put a phosphate group on C8

Put a carboxyl group on C10

Put H’s on all C’s as needed so that every C is
participating in 4 bonds

Include in your diagram: the polarity of the hydroxyl
group, the ionization of the amino and carboxyl groups,
and the double ionization of the phosphate group.
