Q.

We know that for Aromatic Compound the common names are more important but from where I will get those names.

If you any websites then send me the link on my E-mail (anmolnpav@gmail.com) or simply answer me.

In case you yourself have those names then write down them and give me and answer.

Please don't send any screen shot.
