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


        1. 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)
