On the displays, you can see rings consisting of several lines and
|
|
bonds (lines). All points on rings and bonds that do not have a
|
|
notation mean a C atom (carbon) filled with H atoms (hydrogen) such
|
|
that the valence of 4 is satisfied.
|
|
|
|
For example, suppose you have just a single line without any
|
|
characters. That means a bond. It has two points, one at each end of
|
|
the line. So each of these points stands for a C atom, the bond
|
|
itself connects these 2 C atoms. To fulfill the valence of 4, each
|
|
points has to carry additionally 3 H atoms. So the single empty bond
|
|
stands for CH3-CH3, though this combination doesn't make much sense
|
|
chemically.
