Hi, When treated with C2H5OK in C2H5OH, diastereomer A (and its enantiomer) give cis-2-butene without loss of deuterium and trans-2-butene with loss of deuterium. Diastereomer B (and its enantiomer) gave trans-2-butene without loss of deuterium. What is the stereochemistry of elimination here, which accounts for the findings? A B

thanks. i understood when i converted it to saw horse projection. yes morrison boyd is very useful, actually i use O.P agarwall and morrison boyd for organic chemistry. M.B helps strengthening the concepts. If u want to look at more problems, use Arihant. is peter sykes good? i have not come acrtoss it.
