Answer:
Until the mid-20th century, most organic compounds were distinguished from one another largely on the basis of simple physical and chemical properties. Knowledge of these properties, however, yields only superficial clues about a compound’s molecular structure, and the determination of that structure was a complicated process (for large molecules at least) that involved careful analysis of several reaction pathways. Chemists had no way to see what molecules looked like, because molecules are so small that no device such as a microscope could be developed that would give a complete image of a molecular structure. One technique, X-ray crystallography, can give precise structural data for some molecules, but only those that can be obtained in solid, crystalline form. Normally, a full X-ray structure determination is a costly, time-consuming endeavour that is applied to only the most puzzling structures. Sufficient information to decipher a molecule’s structure is much more easily obtained by the use of one or more spectroscopic techniques.
