2/25/2011 1 276 413 347 Is the following reaction thermodynamically favorable? (the average bond energies in kJ/mol are the numbers shown below) A = yes B = no = 689 kJ/mol = 738 kJ/mol 391 What is the best reaction mechanism for this reaction? What would have to be the first step? Are vinyl C-H bonds acidic? A = yes B = no What is the best reaction mechanism for this reaction? What would have to be the first step? Do aromatic C-Br bonds react in substitution reactions S N 1 or S N 2? A = yes B = no When these reactants are mixed together does the following reaction occur? A = yes B = no When these reactants are mixed together does any reaction occur? A = yes B = no Why does this reaction occur when Pd is added? A. The Pd stabilizes the products of the reaction. B. The Pd provides an alternate pathway leading to the products. The Heck-Mizokori reaction C. The Pd increases the acidity of the C-H bond. D. The Pd increases the leaving group ability of Br.
