Including protonations and deprotonations, the reaction takes 12 steps. Write out the mechanism on a sheet of paper and then draw the structure of the product of step 6. • You do not have to consider stereochemistry. •You do not have to explicitly draw H atoms. • Do not include lone pairs in your answer. They will not be considered in the grading. • In an elimination step, include the structure of the leaving group, but draw it in its own sketcher. Separate structures with + signs from the drop-down menu. ? Sn th Previous Nextarrow_forward
