ethylamine does not provide any product (1). However, when Ill is exposed to identical conditions, product IV is isolated as the major organic product. Using arrows to indicate the flow of electrons, explain the formation of IV from III by providing a step-by-step mechanism. Messy or incoherent steps/structures will receive reduced or zero credit. Clearly indicate formal charges and stereochemistry if applicable. a) excess CH, NH, solvent TOH b)H,0* - workup IL H This product...
