Circle the compounds that are aromatic:

Question 18 Determine whether the following compounds are aromatic, anti-aromatic or neither. BH anti-aromatic aromatic neither

Circle the aromatic compounds

56) Which of the following compounds is not aromatic? N: N: II. I. N II. N IV. | N A) I В) П C) II D) IV |

please help with this question. thank you.  Classify the following compounds (if flat) as aromatic, antiaromatic, or nonaromatic.

A. The Cycloheptatrienyl cation is very unstable although it has seven resonance structures, however cyclopentadienyl cation is stable ever it has less resonance structure. B. Why are the following conversions poor synthetic methods to prepare the desired products? + OH2* Does not give H20

How come the structure labeled as 1 has 8 pi electrons? If the double bond has 2 pi electrons, and you count the lone pairs, wouldn't it have 6 pi electrons?  Why does the structure labeled as 2 has aromaticity? If the pi bond has 2 pi electrons and then you coun the lone pairs, wouldn't it only have 5 pi electrons?

question 6. Which of the following is anti-aromatic?

Determine the compound, which is not aromatic in the given compounds. CH3 B. O A CH3

2. Which structure is NOT aromatic? a d. H3C :Br: DO
