the picture of C_{6}H_{6} you will get something like this:

| | | | | |
-C-C-C-C-C-C-
| | | | | |
H H H H H H

which is an absurdity because more than half of the carbon hands are
waving wildly around asking to be held by something. Benzene,
C_{6}H_{6}, evidently is like hexane, C_{6}H_{14}, in having a chain of
six carbon atoms, but it has dropped its H's like an Englishman. Eight
of the H's are missing.

Now one of the men who was worried over this benzene puzzle was the
German chemist, Kekulé. One evening after working over the problem all
day he was sitting by the fire trying to rest, but he could not throw
it off his mind. The carbon and the hydrogen atoms danced like imps on
the carpet and as he watched them through his half-closed eyes he
suddenly saw that the chain of six carbon atoms had joined at the ends
and formed a ring while the six hydrogen atoms were holding on to the
outside hands, in this fashion:
