22. a. Label the reactive features of the following reactants, select the most reactive feature, then write and highlight what it needs. Also, state if a carbocation, carbon radical, or carbanion will start to develop, and/or if aromatic character will be lost as a result of a reaction between these molecules. d-caprolactone with 2 equivalents of ethylamine b. Use mechanism arrows to illustrate the reaction that occurs. If applicable, use stabilization resources to deal with the carbocation, carbon radical, or carbanion that starts to develop during the reaction, and draw the structure of any resonance- stabilized intermediate. Continue labelling and diagramming the reaction until you find the major stable product(s). Finally, state the stereochemistry of the major product(s) and use either Fisher projection or perspective formula representations to illustrate that stereochemistry.
