WebThe p K a of cyclopentane is > 60, which is about what is expected for a hydrogen that is bonded to an sp3 carbon. Explain why cyclopentadiene is a much stronger acid (p K a=15), even though it too involves the loss of a proton from an sp3 carbon. Match the words in the left column to the appropriate blanks in the sentences on the right. WebCyclopentadiene has an unusually low pKa of 15, whereas cycloheptatriene has a much higher pKa of 36. Please explain this difference in pKa using the structures of conjugate bases to aid in your justification. (1 point) pKa = 15 pKa = 36 This problem has been solved!
