just need (e) to (h) 5. Molecules with an-OH group directly bonded to a C-C sp hybridized carbon are called "enol"'s. The types of chemical reactions which enols undergo are substantially different from those of normal alcohols. By considering the Brensted-Lowry and Lewis acid/base reactivity of an enol, you can predict a few of these differences. (a) Ethenol, the simplest "enol", can react as a BL. base in three different places, by gaining a proton at either of the two...
