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...
Question 2. Consider the following 8 bundles of goods x and y: A = (8,4) B = (5,6) C = (5,9) D = (10,3) E =(1,4) F =(6,5) G=(2,8) H =(7,8) (a) Come up with an example of a utility function that will produce the following order of preference for the bundles, where H is most preferred, A and G are equally preferred, and E is least preferred. H , C , B , F , A = G ,...
