Title: pKa of alpha hydrogen regarding n-Ethyl propionate
Post by: Beatle on January 13, 2018, 07:05:20 AM

Im wondering where or how I can find the pKa of a hydrogen alpha to the carbonyl of n-Ethyl propionate.

Have you checked Williams' table of pK_a values?

Williams gives a value for one ester as about 24.5.  When using any table, I would pay attention to whether the pK_a was determined in water or in DMSO.
