Webcharacterize. Perhaps the most famous is the water/ethanol/ benzene azeotrope (bp 64.9°), which has a lower boiling point than even the water/ethanol azeotrope (78.2°C). So one trick to making 100% ethanol (anhydrous or absolute ethanol) is to add a bit of benzene (the carcinogenic one) to the 95% ethanol/water mixture. Now the benzene/water/ Web1.

So in the first step, you want it to react with your carbonyl. And the second step, once it's reacted with the carbonyl, it's OK to add water in the form of H3O plus. And this is going to form our alcohol. twitter fact-checks this biden claim
