How to Draw Different Isomers.

Changing the shape of the molecule does not produce
a different isomer. A different isomer can only
be made by changing the way in which the
carbon atoms are joined together (see previous page).

Look at the these illustrations of isomers of pentane below.

n-pentane Isomer of Pentane

n-pentane Same Isomer of Pentane showing Different Shape

These isomers are all the same. Although the shape
of the molecule has been changed, if you look at the way
in which the carbon atoms are joined to each other,
you will see that isomers 2 and 3 are the same as isomer 1.
