Add the pi electron structure for benzene.

[tajwarhq]

Hi, I'm a student in the UK. For the vast majority of cases, the skeletal formula of benzene that showcases the pi bonding structure (the hexagon with the circle in the middle) is the only relevant skeletal model. The alternating double bonds represent the Kekulé model which is considered "wrong" in most syllabi at my level of education.

I would appreciate it if the pi bonding model could be added.

Thanks.

Hi Thanks for the suggestion. At the moment we don't offer the 'Thiele notation' for the representation of pi-systems. This has fallen out of fashion in recent years, especially in academic journals. This example from my own branch of chemistry) is pretty typical: We are planning to investigate respresentation of delocalised systems at some point. These would include arenes, arene ligands and allyl systems. We'll probably end up adopting the approach outline in this publication: https://cheminf20.org/2018/01/03/bond-artifacts-cheminformatics-and-aesthetics-for-inorganic-structures/ We'd appreciate any input you'd like to make into the requirements for this feature!
