The pKa of cyclopentadiene (I) and cycloheptatriene (II) are around 16 and 36 respectively. Which of the following is not a valid explanation for the large difference in the two pKa values?



◦ The conjugate base of cyclopentadiene (I) is an aromatic anion.
◦ The conjugate base of cycloheptatriene (II) is less stable due to aromaticity.
◦ If the conjugate base of cycloheptatriene (II) was flat it would be antiaromatic.
◦ The conjugate base of cycloheptatriene (I) is a nonaromatic anion.
◦ The conjugate base of cyclopentadiene (I) is more stable due to aromaticity.
