WebCarboxylic acids are considered relatively weak acids with typical pKa values between 4 and 6. For instance, acetic acid (the one that you find in table vinegar) has pKa=4.75 while a sulfuric acid (your typical strong acid) has pKa=-3. So, your typical strong acid is over ten million times more acidic than a typical carboxylic acid. WebOxidation The oxidation of primary alcohols is a common method for the synthesis of …
