# Is the middle ring of this organic compound aromatic?

Is the middle ring with 5 atoms of (4⁠Z)-4-[(4-methoxyphenyl)methylidene]-5-methyl-2-phenyl-2,4-dihydro-3⁠H-pyrazol-3-one aromatic?

The carbonyl group could become a negatively charged oxygen, the tertiary amine could then form a double bond with the $\ce C$ atom of the carbonyl group. The secondary amine could contribute one electron to the $\pi$-system. And the $\ce C$ atom of the ethen-group could contribute two electrons if the other $\ce C$ atom becomes positively charged, but I'm not sure if this is likely.

• It's hard to know for sure without computing or an experiment. But with the methoxy on the phenyl ring, I am definitely inclined to think that it is more aromatic than not. – Zhe Jul 10 '17 at 21:19
• @Zhe: Thanks for your comment, I am also inclined to think that this ring is aromatic. – Jadzia Jul 15 '17 at 10:23
