Functional Groups, Structures, Nomenclature (20 pts)
1. (4 pts) Draw line-bond structures for two different secondary amines with the formula C5H11N
[2(5) + 2 - 11 + 1]/2 = 1, so there must be either one ring or one double bond. There are many possible correct
answers.
H
N
NH
2. (4 pts) Draw line-bond structures of two different ketones with the formula C7H12O
[2(7) + 2 - 12]/2 = 2, and a ketone has one C=O, so there must be one other unsaturation in the form of a double
bond or a ring. There are many possible correct answers, three variations are shown (only two are required)
O
O
O
3. (6 pts) Underneath the structure, write the name of each of the following:
Br
4-bromo-5-ethyl-2,2,3-trimethylheptane
3-isopropyl-1,1-dimethylcyclohexane

4.
Quiz 2h
(2 pts) Draw a line-bond structure for 1-t-butyl-2,3-dimethyl-cyclopentane
5. (4 pts) Draw a Newman Projection for a staggered conformation of 2,3-dibromobutane
looking along the C2-C3 bond.
H
Br
CH 3
Br
CH 3
H
There are several correct answers, but all correct answers have one CH3,
one Br, and one H on the front carbon, and one of each on the rear carbon.
