I have a question, just out of interest: Let's assume I protonate the OH group and split off H2O. Then a stable carbenium ion should be formed, right? Is there a way to simply “add” an H to this C+ to simply get a neutral molecule again? So like the third picture.11mo ⋅ Witty_Company_8489 ⋅ r/chemhelp
