Title: Benzene ring with no hydrogens
Post by: killertaco on July 28, 2021, 05:48:23 PM
Hello, this is my first post here so I'll get straight into it (apologies for incorrect formatting of the question, I'm just curious)

This might be an easy to answer question but, is it possible to have a benzene ring with no hydrogens at all?
So there would be alkyne bonds in the place of all the previous alkene bonds. I know that it isn't possible for there to be alkene bonds the entire way around the ring because of something to do with 'bending' that my teacher briefly explained but she didn't say whether or not this is possible.

Thank you :)

Here you can se that the so called sp-bonds in alkynes are straight, bending is possible but not so much:
