For the following dehydrohalogenation (E2) reaction, draw the
Zaitsev product(s), showing the stereochemistry clearly. If there
is more than one organic product, both products can be drawn in the
same box.the hint:Consider that the reaction is an elimination in the presence of
a relatively small base to give the Zaitsev product, which is the
most stable. Also consider the stereochemistry...

not sire if im right or wrong?
Consider the following reaction at equilibrium. What will happen if Fes, is removed from the reaction? 4 FeS (s) + 11 O2(g) = 2 Fe,0,(s) + 8 SO,(9) looo The equilibrium constant will increase. The equilibrium will change in the direction of the reactants. The equilibrium will change in the direction of the...

T ylic uelydration reaction, draw the curved arrow mechanism leading to the major alkene product and one of the minor alkene products. Draw a picture of the hyperconjugation interaction that explains the greater thermodynamic stability of the major product versus the minor product. Concisely explain why the uncatalyzed dehydration reaction would not form the carbocation intermediate Me catalytic H2SO4 -он...
