please answer all parts, thanks!
1. More substituted alkenes are more stable than less substituted alkenes. Show the orbital overlap that helps to explain this observation. 2. Why is the heat of hydrogenation for an alkene exothermic? Analyze the bonds that are changing. AH = -30 kcal/mol Explain: + H2 3. Treating alkene "A" below with HBr can lead to a number of products. "A" SM + H-Br A bunch of products. For real, hella products. 3.A. Label the stereocenters...

3. Draw a stepwise, detailed mechanism for the acid-catalyzed hydration reaction in question 2 above. Use curved arrows to indicate the flow of electrons. (Note: use hydronium ion, H307, in your mechanism to indicate "acidic water"). (6 pts) 4. Draw a stepwise, detailed mechanism for the reaction below. Use curved arrows to indicate the flow of electrons. (Hint: think of this reaction as a combination of addition of HX (step 1) and hydration (step 2)]. In the second step, an...
