✦ Synopsis

Inreamxugmieut, exchange and solwlyeis reactions of neutral organic eubstratee proceeding by way of carbouium ions, it is important to dietiuguishbetweeniouiaatiou and dissociation and to consider explicitly the role of different ionic intermediates representing various stages of ioni~atiou-dieaociatiou2*3. In fact, a coueiderable body of iufonuation is now available anthe intimate couree of carboniumion reactions of allyllc,hoBMllylic~variouerat~~~~giag~t~ 2~3. we have now compare6 the rate6 of racemisation and radio-chloride exchange of pchlorabenshydrglchlorideinacetone rolvent. Three differ by a eubetantial factor and therefore give ccneiderable ineight into the behavior of the ionic intermediates inwlved.
