Question: In the presence of sulfuric acid, what is the product of the electrophilic substitution of benzene with sulfur trioxide?

Options:

Correct Answer: Benzene sulfonic acid

Solution:

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

In the presence of sulfuric acid, what is the product of the electrophilic substitution of benzene with sulfur trioxide?

In the presence of sulfuric acid, what is the product of the electrophilic substitution of benzene with sulfur trioxide?

Step 1: Understand that benzene is a type of hydrocarbon with a ring structure.
Step 2: Know that electrophilic substitution is a reaction where an electrophile replaces a hydrogen atom in benzene.
Step 3: Recognize that sulfur trioxide (SO3) acts as the electrophile in this reaction.
Step 4: Realize that sulfuric acid (H2SO4) helps generate the electrophile (SO3) and facilitates the reaction.
Step 5: When sulfur trioxide reacts with benzene, it substitutes one hydrogen atom on the benzene ring.
Step 6: The product formed from this substitution is called benzene sulfonic acid (C6H5SO3H).

Electrophilic Aromatic Substitution – This reaction involves the substitution of a hydrogen atom on the benzene ring with an electrophile, in this case, sulfur trioxide (SO3), facilitated by sulfuric acid.
Formation of Benzene Sulfonic Acid – The product of the reaction is benzene sulfonic acid, which is formed when the electrophile (SO3) reacts with benzene.
