Unlike most other electrophilic aromatic substitutions, sulfonation is often reversible. When toluene is sulfonated at 0 °C or at 100 °C, the following ratios of substitution products are obtained: Isomer of the product T = 0 °C T = 100 °C o-toluenesulfonic acid 43% 13% m-toluenesulfonic acid 4% 8% p-toluenesulfonic acid 53% 79% a) Explain the change in the product ratios when the temperature is increased.
