What is chirality and how did it get in my molecules? - Michael Evans
Improve your understanding of molecular properties with this lesson on the fascinating property of chirality. Your hands are the secret to understanding the ...
========== In the early days of organic chemistry, chemists understood
that molecules were made of atoms connected through chemical bonds. However, the three-dimensional
shapes of molecules were utterly unclear, since they couldn't
be observed directly. Molecules were represented using
simple connectivity graphs like the one you see here. It was clear to savvy chemists
of the mid-19th century that these flat representations
couldn't explain many of their observations. But chemical theory hadn't provided
a satisfactory explanation for the three-dimensional
structures of molecules. In 1874, the chemist Van't Hoff
published a remarkable hypothesis: the four bonds of a saturated carbon atom point to the corners of a tetrahedron. It would take over 25 years for the quantum revolutio...
