1.	The addition of mercury changes the orientation in a number of aromatic sulfonation reactions.(a) True(b) FalseI had been asked this question by my college director while I was bunking the class.Asked question is from Catalyst and Sulfonating Agents topic in section Sulfonation and Sulfation of Unit Processes
Answer» CORRECT choice is (a) True Explanation: The ADDITION of mercury changes the orientation in a number of aromatic sulfonation REACTIONS. This is of great practical importance especially with anthraquinone, since in the PRESENCE of the catalyst the a-sulfonate is formed almost exclusively, while without mercury only the, B-sulfonate is OBTAINED.
