What is the difference between the two naphthenes in this table?

[mech-eng]

In this table there are two different naphthene so this confuses me.

 

[adjacent]

They are saturated and non saturated Naphthene .

Why arent there any explanation for aromatic in the table and benzene and unsaturated naphthene are written under aromotic so are benzene and unsaturated naphthene are aromatic but saturated naphthene not?

 

[Borek]

What does it mean "aromatic"?

Do you understand the difference between benzene and cyclohexane?

 

[mech-eng]

Look at the table in the pic, there is no info for aromatic and there are benzene and the other
naphthene.

I agree table is not especially good, but formulas given explain rather well what is what. Especially when you know the answers to the question I posted earlier.
