Currently over twentymillion compounds have been reported in thechemical literature; about 90% of them areorganic, ie they contain carbon. The remainingcompounds are called inorganic and are formedfrom the other elements, of which there areabout 100. That carbon so dominatescompound formation is a result of the fact that itis almost unique in its ability to form longchains with other carbon atoms.
using an Abbé refractometer where the liquid is placed on a glass prism of known index of refraction. [Glass is easier to work with than a vacuum.] Because of the large number of electrons located around the ring in aromatic compounds these compounds usually …
