Chem 321 Exam 3

reaction in which the product distributions is determined by the relative energies of the products.

reaction in which the product distribution is determined by the heights of the different transition states leading to products

states the transition state for a reaction will more closely resemble the higher energy molecule (i.e. the products for an endothermic reaction and the reactants for an exothermic reaction)

difference in energy between the starting materials and the products

heat of reaction or measure of the bond energy changes in a reaction

measure of the change in order between the starting materials and products

reaction where products are more stable than reactants

reaction where reactants are more stable then products

states that a system at equilibrium responds to stress in a way to relieve the stress

reaction rate depends solely on the concentration of one species

reaction rate depends on the concentration of two species

reaction where the concentration of one of the reactants does not change during the reaction

states that if the mechanism of the forward reaction is known, then the mechanism of the reverse reaction must also be known

elimination where the dihedral angle between C-L and C-H is 0°

elimination where the dihedral angle between C-L and C-H is 180°

outcome of a reaction where more than one orientation of substituents is possible in the product

less stable alkene

more stable alkene

crystallization, distillation, chromatography

NMR spectroscopy, IR spectroscopy, Mass spectrometry, UV/vis spectroscopy

addition of water to a pi bond

formation of an alcohol
