Does reaction of molecular iodine with nitric acid not produce iodobenzene in greater yield? Lesser yield? Just as good?

Thanks!

but u forgetted that HI is reducing agent that can reverse the reaction toward the benzene ring

HI is not a reducing agent.

My text said that HI is a reducing agent.(That’s why direct Iodination fails to give Iodoalkane. Prescence of oxidising ahents like HgO is required to oxidise hydrogen iodide to iodine gas)

Check the description reaction, its CuI instead of CuCl2
