What is the product of the sulfonation of benzene using sulfur trioxide (SO3)?

What is the product of the sulfonation of benzene using sulfur trioxide (SO3)?

Step 1: Start with benzene, which is a ring of six carbon atoms with hydrogen atoms attached.
Step 2: Introduce sulfur trioxide (SO3) to the benzene. This is a chemical reaction where SO3 acts as an electrophile.
Step 3: The sulfur trioxide attacks the benzene ring, replacing one hydrogen atom. This is called electrophilic substitution.
Step 4: After the reaction, the product formed is benzene sulfonic acid, which has a sulfonic acid group (-SO3H) attached to the benzene ring.
