2. Will the following reaction occur as written? HO, NH H2N cat. H2SO4 A) Yes, after initial protonation of the carbonyl oxygen, ethanol is added to open the lactam. B) No, the lactam would dimerize under these conditions. C) Yes, cyclic amides can easily be converted to esters due to the ring strain. D) No, ring opening of the lactam does not occur since the protonation of the nitrogen occurs more readily than protonation of the carbonyl oxygen.
