My answers for part a seem right being the image at the bottom, I do not understand why it is wrong. The 2nd answers for part b is just a heptanamide and ammonium and a chloride ion in different answer sections again. I don't know why or which of these is are wrong.

a. Draw the structure of the tetrahedral intermediate INITIALLY FORMED in the reaction shown. - You do not have to consider stereochemistry. - Do not include counter-ions, e.g., Na+,I, in your answer. - In cases where there is more than one answer, just draw one. b. Draw the structures of the final acyl transfer products obtained. - You do not have to consider stereochemistry. - Draw organic products only. - Draw the neutral form of the products; no charges. - Draw one structure per sketcher.
