Question

4. (Basicity and equilibrium) Complete the following reactions: you must show more than one possible mechanisms before you choose the better one with a greatly detailed explanation. Then, explain the equilibrium and the explanation must be done in terms of basicity of each compound. (6 pts) H2SO4 + CH,00 NHOH

Answer 1

Hydroxamine acid HHOH + H2 NH2 + NH,OH = ammonia amide of Amidane In this reaction amide is te Basic that the hydroxamic acid. Became the loan pairs of Nitrogen act for Ancleophile But in care -hydroxamic auld the ot group attached to bapako NH group so it aets very stronger - Hucleophile. In the above reaction mixture the equilibrium of hydroxamic auld more stable than the amide side equlibrium. Became recut ant bese in highce energy compare to. the product. the products all at wwer energy ③ H₂SO4 + CH₃coo = CH₂cooH+ Hso In this reaction H₂So is the strong auid compaire to acetic acid so deetic anfon gein proton the Maso, & form auchte auld so the right side equilibrium more stuble than the left side equlibrium. 45o2- quite stable & also more basic than encoo because in checoo one donating group is present so acetic anion B quite less stable than Hsor
