What is the full arrow pushing mechanism for the following transformation?
Hint: Remember, show all steps to convert the starting material
into the product. Do not skip steps for full credit. You have to
show how ALL bonds are breaking and forming for this transformation
to occur.

Provide a reasonable arrow-pushing mechanism for the following transformation. (Hint! The reaction involves both intramolecular v. addition and aldol reactions. C1 is labeled in the starting material and product.) NaOE/EtOH но
Write the product and a complete arrow-pushing mechanism and propose (the) major product(s) for the following transformation. After a Grignard reaction. .... Each of the Grignard reactions we have studied so far produces an alcohol as the major organic product. Alcohols can be used as starting materials for a number of organic reactions. Use this exercise to consider the range of reactions that can be performed after a Grignard reaction. For each reaction sequence below, suggest a Grignard reagent and...
