Abstract
THE improved electron diffraction method1 of determining molecular structure in the vapour phase has brought to light the fact that the distance between a carbon and halogen atom depends on the character of the binding attaching the carbon atom to other atoms in the system. Hitherto, the magnitude of this distance has been regarded as constant. We have shown that the carbon-halogen distance is smaller in aromatic compounds than are the accepted values for the aliphatic series2. This suggested that an investigation of certain aliphatic, ethylenic and acetylenic compounds by electron diffraction might throe more light on this question.
