what did i do wrong here. , it seems to be marking it wrong but i thought it needed to be protonated Consider the reaction of a ketone with a secondary amine to form an enamine. A key intermediate formed in the reacarbinolamine. Draw curved arrows to show conversion of the carbinolamine to the enamine, then draw the product+PhaHEnamineDo not delete any pre-drawn bonds, charges, or lone pairs. If you accidentally delete a vital part of the structure, clibutton in the lower left.Step 1: Add curved arrows to thecarbinolamine intermediate.PhHN1LStep 2: One of the curved arrows as beenpre-drawn for you. Add a second curved arrow.ДمعيرPh
