Consider the following two compounds A and B below and answer the questions that follow. Note that both compounds dehydrate upon the addition of a base through the E2 mechanism. OH OH HCM CH2CH3 H:C. CH,CH; H3C HC CH; CH; CH; CHZ A B a) Draw the most stable chair conformation for Compound A. (1) b) Draw the least stable chair conformation for Compound A. (1) c) Draw the most stable chair conformation for Compound B. (1) d) Draw the least stable chair conformation for Compound B. (1) e) Which of the two compounds (A or B) would dehydrate faster in the presence of a base? Explain your answer by using notes AND mechanisms (use chair conformations and show curly arrows!!!) for the dehydration processes for BOTH A and B! THUS draw the product (or products) that one would expect in the case of BOTH A and B. (8)
