I have read that the(adsbygoogle = window.adsbygoogle || []).push({}); of almost all organic molecules can be represented visually as Planar Graphs, i.e. 2-dimensional lattice-like structures consisting of nodes (points) connected by lines in whichstructureFrom the perspective of Physical Chemistry, does anybody know why this is so? Some graphs are of such complexity that they required 3 dimensions to guarantee that no lines cross - reference "3 Utilities Puzzle".no lines cross.
