Aromaticity and the Huckel 4n+2 rule Flashcards
1
Q
molecule is aromatic only if it has a planar, monocyclic
system of conjugation and contains a total of 4n pi electrons (4, 8, 12…)
A
False. contains a total of 4n+2 pi electrons.(6, 10, 14…)
2
Q
4n pi electrons can be aromatic
A
False. it CANT be aromatic. Rather, ANTIAROMATIC. Due to delocalization of pie electrons that would lead to their destablization.
3
Q
Requirements of Aromaticity:
- Non-Planar
- pi electrons follow Huckle rule 4n+2
- Has continuous conjugated doubke bon in a ring.
A
False.
- PLANAR
- pi electrons follow Huckle rule 4n+2
- Has continuous conjugated doubke bon in a ring.
4
Q
Is benzene aromatic
A
True. Has 6 has six pi electrons following huckles rune nf+2
