1.	Sulfonation like iodination is reversible and is believed to take place in concentrated sulfuric acid via the following pathway Find the correct statement(s) for above given reaction
Answer» BENZENE is sulfonated fairly slowly by hot concentrated sulphuuric acid but rapidly by oleum. (RATE than being related to `SO_3` content) In Oleum , the ` sigma`-complexbelieved to UNDERGO protonation of `SO_3^(Ɵ)` before undergoing C -H fission KINETIC isotope effect exhibit because `k_a GE k_2 ` Rate of sulphonation reaction `= C_6H_6 gt C_6D_6 gt C_6T_6` Solution :Benzene Sulfonation
