5. Heck Reactions: Consider the following reaction: Pd atalyst yº syn-elimination of HPI T trars-configuration of double bond a) The configuration of the double bond in the above reaction is predominately trans. This can be explained by drawing a Newman projection of the intermediate in the brackets. The elimination of HPdI is syn (from the same side), An eclipsed conformation is required. - Please complete the partially drawn Newman below by replacing the question marks by the missing phenyl group...

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...
