What is the product of the electrophilic substitution of toluene with sulfuric acid?

What is the product of the electrophilic substitution of toluene with sulfuric acid?

Step 1: Understand that toluene is a compound made of a benzene ring with a methyl group (CH3) attached.
Step 2: Know that sulfuric acid (H2SO4) is a strong acid that can act as an electrophile in reactions.
Step 3: In an electrophilic substitution reaction, the electrophile (sulfuric acid) attacks the benzene ring of toluene.
Step 4: The methyl group on toluene makes the benzene ring more reactive towards electrophiles.
Step 5: The sulfuric acid adds a sulfonyl group (SO3H) to the benzene ring, replacing one hydrogen atom.
Step 6: The final product of this reaction is toluene sulfonic acid, which has the formula C7H8O3S.
