The oxidation of naphthalene in presence...

The oxidation of naphthalene in presence of catalyst `Hg//H_(2)SO_(4)` to Phthalicacid. How many moles of `SO_(2)` is formed ? (`CO_(2)` evolved)

Verified by Experts

The correct Answer is:

`underset("Naphthaline")(C_(10)H_(8)+9H_(2)SO_(4)) overset(Hg)to underset("pnthalic acid")(C_(8)H_(6)O_(4)+H_(2)O) +9SO_(2)+2CO_(2)`
