TAILIEUCHUNG - Four Lectures on Mathematics, by Jacques Hadamard

In organic chemistry, there can be more than one chemical compound with the same composition and molecular weight. Generally, these are called isomers. Isomers usually have substantially different chemical properties, may be isolated and do not spontaneously convert to each other. A common example is glucose vs. fructose. The former is an aldehyde, the latter is a ketone. Their interconversion requires either enzymatic or acid-base catalysis. However, there are also tautomers, where isomerization occurs spontaneously, such that a pure substance cannot be isolated into its tautomers. A common example is glucose, which has open-chain and ring forms. One cannot manufacture. | Project Gutenberg s Four Lectures on Mathematics by Jacques Hadamard This eBook is for the use of anyone anywhere at no cost and with almost no restrictions whatsoever.
