Write a note on benzyne intermediate
Hello,
Benzene intermediate is a a positive ion which has broken the pi ring system.
Here's a image to get an better understanding: http://alevelchem.com/img/nitration_benzene.gif
You can also see two double bonds in the image of Benzene intermediate, so there are two pairs of electrons in pi bonds.
It is a molecular orbital spread over four centres.
Hope this helps and all the best to you!
