NEET levelSingle correct optionDifficulty 1 of 3g3172

Naphthalene is sulfonated with concentrated $H X_{2} SO X_{4}$ at $80^{\circ} C$ for a short time. The major product is

Anaphthalen-1-ol
Bnaphthalene-2-carboxylic acid
Cnaphthalene-2-sulfonic acid
Dnaphthalene-1-sulfonic acid

Answer: D

At

80^{\circ} C

the reaction is under kinetic control, and attack at C-1 is faster. The product is naphthalene-1-sulfonic acid.
