Problem: Answer the following questions regarding cyclopropane and propane. a. Provide an approximate pKa value for the C-H bond of propane. b. Using pictures and a minimum amount of words, name and describe the types of strain associated with cyclopropane. c. The Csp3 orbitals are able to relieve some of the strain by adjusting slightly. Draw a molecular orbital representation of cyclopropane. d. Please provide a name for the type of “adjusted” bonds you drew in part c. e. Due to the reorganization of the hybrid orbitals in cyclopropane, the s character of the carbon-hydrogen bonds actually increases. Do you think this will increase or decrease the pKa value of a C-H bond in cyclopropane? Why or why not?
