The following substances can be prepared by a nucleophilic addition reaction between an aldehyde or ketone and a nucleophile. Identify the reactants from which they were prepared. If the substance is an acetal, identify the carbonyl compound and the alcohol; if it is an imine or enamine, identify the carbonyl compound and the amine. You do not have to consider stereochemistry. In cases where there is more than one answer, just give one. Use Grignard reagents when an organometallic reagent is required. Draw the Grignard reagent as a covalent magnesium bromide. LOH OH 888

Vrite the equations that r

Adding heat to a reversible endothermic reaction at equilibrium will _________.   decrease the amount of product   increase the amount of reactants   shift the equilibrium to the left   all of the above   none of the above

Reactions generally either release or absorb heat when they occur. Based on your temperature observations, is the equilibrium reaction 1 exothermic (heat producing) of endothermic (heat consuming)?  Hint:  consider what happens if you treat “heat” as a chemical species that is either a reactant or a product (USING THE TABLE).

list several attributes that are used to compare the “greenness” of a solvent and explain why catalyst are useful in making reaction greener
