Homework Answers
here's the mechanism of reaction. This will help. Basically th
acidification comes in that carbonile, because it has the Beta
carbon with the most acidic hydrogen. The other carbonile has a
double bond near by so, the acid character is lowered. See picture
for mechanism of reaction:

Account for the
regioselectivity and stereoselectivity observed when this compound
is treated with BH3 by drawing the product formed prior to a
subsequent hydrolysis reaction.
Account for the regioselectivity and stereoselectivity observed when this compound is treated with BH; by drawing the product formed prior to a subsequent hydrolysis reaction. • Use wedge and hash bonds ONLY when needed to show reaction stereochemistry • If the reaction produces a racemic mixture, just draw one stereoisomer.

Choose the correct reaction coordinate diagram for a two-step reaction in which the first step is endergonic, the second step is exergonic, and the overall reaction is endergonic. Pay attention to the reactants, products, intermediates, and transition states A reactants) B = first transition state C = intermediate D = second transition state E =product(s) Free energy Progress of the action A = reactant(s) B = intermediate C = first transition state D = second transition state E = product(s)...

What is the difference between a first order and a second order reaction? a. For a first order reaction, plotting the natural logarithm of A versus time always gives a straight line with a slope equal to -k For a second order reaction a plot of 1 / A versus time, will produce a straight line with a slope equal to k b. For a first order reaction, plotting the natural logarithm of A versus time always gives a straight...
