Trihydrogen cation
WebIn the pentadienyl anion, the negative charge is centred on the carbon atoms in the 1,3 and 5 position - similarly with the positive charge for the cation. These ions are represented in resonance theory as two or three canonical forms: The delocalisation of p-electrons is associated with a lowering of the orbital energy.
