Carbon or Nitrogen with five bonds is not allowed. The general approach is described below: Benzene is a common organic solvent that was previously used in gasoline; it is no longer used for this purpose, however, because it is now known to be a carcinogen. In this case, however, there are three possible choices: As with ozone, none of these structures describes the bonding exactly. Download Latest Resonance formula Booklet pdf for JEE Main 2020 .
