摘要

Abstract-The ultra-violet absorption spectra of 31 mono-aryl carbinols in concentrated sulphuric acid have been measured. The results provide direct evidence of the dependence of carbonium ion stability upon inductive and space-polarization effects. ... WHEN carbinols or olefins are dissolved in concentrated sulphuric acid, intense ab- sorption bands are observed in the near ultra-violet. These bands have been attributed to the formation of stable carbonium ions l - ...
