Question:medium
Give the possible structure of X in the following reaction: C₆H₆ + D₂SO₄ xrightarrowD₂O X
Give the possible structure of X in the following reaction: C₆H₆ + D₂SO₄ xrightarrowD₂O X
Show Hint
• Sulfonation of benzene is reversible
• In D₂SO₄/D₂O, repeated sulfonation–desulfonation causes full H/D exchange
