IDENTIFY ANY PARTICULAR STABLE OR UNSTABLE INTERMEDIATES AND DETERMINE IF THE SUBSTITUTION IS ORTHO, PARA, OR META DIRECTING BASED ON THE RELATIVE STABILITY OF THE INTERMEDIATES. -t Br meta.
10. Two of the isomers of xylene, C8 H10, are called meta-xylene and ortho-xylene. The equilibrium constant Ke for the reaction m-Xylene o-Xylene is found to be 0.27 at 300° K and 0.55 at 1000° K. Which isomer has the lower ground state? Which has the more closely spaced levels? (Careful!) 10. Two of the isomers of xylene, C8 H10, are called meta-xylene and ortho-xylene.
