Identifying Aromatic Systems
Determine if each of the compounds on the left meet the criteria for aromaticity according to the Huckel (4n+2) convention.Click the mouse on the molecule to view the answer;
click on the button to view the conjugated system.
The molecule contains 4 p-electrons and is not aromatic according to the 4n+2 rule. The p-electrons are shown below:
The molecule contains 6 p-electrons, is cyclic and planar and therefore is aromatic according to the 4n+2 rule. The p-electrons are shown below:
The molecule contains 8 p-electrons and is not aromatic according to the 4n+2 rule; it is also not planar. The p-electrons are shown below:
The molecule contains 4 p-electrons, as shown below:
The molecule contains 6 p-electrons, as shown below:
The molecule contains 8 p-electrons, as shown below:
