Question: What is the product of the reaction of benzene with sulfur trioxide (SO3) in the presence of sulfuric acid?

Options:

Correct Answer: Benzene sulfonic acid

Solution:

The product is benzene sulfonic acid, formed by the electrophilic substitution of sulfur trioxide on the benzene ring.

What is the product of the reaction of benzene with sulfur trioxide (SO3) in the presence of sulfuric acid?

Step 1: Start with benzene, which is a ring of carbon atoms with hydrogen atoms attached.
Step 2: Introduce sulfur trioxide (SO3) into the reaction. This is a compound that can react with benzene.
Step 3: Add sulfuric acid (H2SO4) to the mixture. This helps facilitate the reaction.
Step 4: The sulfur trioxide acts as an electrophile, meaning it is attracted to the electrons in the benzene ring.
Step 5: The benzene ring undergoes a reaction called electrophilic substitution, where one hydrogen atom is replaced by a sulfonyl group (SO3H).
Step 6: The result of this reaction is benzene sulfonic acid, which has the sulfonyl group attached to the benzene ring.
