Explain by drawing the structure why triphenylmethyl cation is so stable? Why carbanion are strong bases whereas carbocations are strong acids?
4. Explain why maleic anhydride is exceptionally reactive and why anthracene is usually unreactive. Explain why did this Diels-Alder reaction proceed? Why does anthracene react from the central ring system and not one of the outer rings?

A chemical reaction produces very stable molecules from highly reactive molecules. The products are two solids, while the reactants are a liquid and a gas. What type of thermodynamic process is this reaction? Why? Endothermic rxn that is increasing the entropy of the system. Thus, it is a Type 4 reaction O Endothermic rxn that is decreasing the entropy of the system. Thus, it is a Type 2 reaction Exothermic rxn that is increasing the entropy of the system. Thus,...
Why is the emulsion in homogenised milk so much more stable?
PRINTER VERSION BACK NEXT Practice Problem 06.29 The following hypothetical compound cannot be prepared or isolated, because it has a very reactive nucleophilic center and a very reactive electrophilic center, and the two sites would react with each other rapidly. Identify the nucleophilic center and electrophilic center in this hypothetical compound: Electrophilic center Nucleophilic center Electrophilic center Nucleophilic center Nucleophilic center Electrophilic conter Electrophilic center Nucleophilic center Version 4
