1) Draw the mechanism for the crossed aldol condensation between 3-hexanone and benzaldehyde.
2) Draw a representation for TPCP that would represent itsstructure if the phenyls were perpendicular to the 5-membered ring(a paddle wheel structure) and a representation that represents the"propeller" structure is chiral. Is the paddle wheel structurechiral or achiral? How do you know?
