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:
