Verified step by step guidance

Identify the starting material: The compound is a benzopyranone, which is a bicyclic structure containing a benzene ring fused to a pyranone ring.

Recognize the reagent: Concentrated sulfuric acid (H₂SO₄) is a strong acid and can act as a catalyst for electrophilic aromatic substitution reactions, such as sulfonation.

Understand the reaction mechanism: Sulfonation involves the formation of an electrophile, the sulfur trioxide (SO₃) group, which can attack the aromatic ring to form a sulfonic acid group (SO₃H) on the benzene ring.

Determine possible positions for substitution: The benzene ring in the benzopyranone can undergo sulfonation at different positions, typically at the ortho or para positions relative to the oxygen in the pyranone ring, due to resonance stabilization.

Analyze the products: The images show different sulfonated products, indicating that sulfonation can occur at various positions on the benzene ring, and all depicted products are possible due to the nature of the reaction and the stability of the intermediates.
