Match each type of formula with the best description of what they are used
to illustrate.
Illustrates all of the bonds in
1 Lewis structure
a molecule
Illustrates the differences
between cis/trans- isomers of 2 Dash-wedge
cyclic compounds
Show the bonds between
atoms without writing the 3 Line-angle
symbol for C and H
Molecular model
demonstrating the 3D
4 Ball and stick
position of atoms and the
bonds between them
Includes each element and
the number of atoms of each
5 Molecular

, Categorize the following pairs of formulas as representing potentially the
same or different compounds
Same Compounds Different Compounds
1 2
Exploration
_____ show all bonds and any non-bonded valence electrons as lone pairs.
Line-angle formula
Molecular formulas
Condensed molecular formulas
Lewis structures

,Condensed structural formulas are the most efficient method of drawing
organic compounds because they do not explicitly show the symbols for
carbon and hydrogen.
True
False
_____ structures include atoms represented by spheres and bonds
represented by rods.
Dash-wedge
Lewis
Line-angle
Ball and stick
_____ occur when compounds with the same formula have atoms arranged in
different orders.
Condensed structures
Lewis isomers
Structural isomers
Stereoisomers
Carbon atoms in cyclic compounds cannot rotate around the bonds within
the ring without breaking bonds.
True
False

, When drawing structures from compound names, _____ are given priority in
numbering carbons over _____.
double and triple bonds; substituents
single bonds; double and triple bonds
single bonds; substituents
substituents; double and triple bonds
Cyclohexane is an isomer of 1-hexene and 2-hexene.
True
False
Cyclic alkanes have the same general formula as _____.
hexenes
hexynes
hexanes
Exercise 1
When drawing a condensed structural formula, how do you determine how
many hydrogen atoms to include with each carbon atom?
To determine how many hydrogen atoms there are to include with each carbon in a
condensed structural formula, simply subtract the number of bonds that carbon makes
with the other atoms from 4. That is how you find out how many hydrogen atoms are
required to fill up carbon's four bond spots.
