Circle the mechanism and draw the major organic product for each reaction. If the alkenehas stereocenters, include stereochemistry, drawing the major configurational isomer formed.Alkenes are planar, so make sure to convert the wedges and dashes on the alkene carbonsinto regular lines to convey the geometry and the stereochemistry. Assume the ionsdissociate-e.g., NaOH is Na* and -OH.(a) Mechanism (circle one): E2 or E1咪H3CNaOH(b) Mechanism (circle one): E2 or E1H3CXxH3COH
