PARACHOR OF SOME ORGANIC COMPOUNDS AND THEIR CHEMICAL CONSTITUTIONS

Parachor of simple pyrone, dimethyl and diethylpyrones have been determined in ethyl acetate and nitrobenzene. The value in case of pyrone and diethyl pyrone approaches more to the simple ring formulae and therefore mast have the structure suggested by Deshapande (\(\jmath\). \(Indian\) \(Chem\). \(Soc\)., 1932. 9, 303), while dimethylpyrone should be re­presented by Collie's bridge-ring structure.
