1. The problem statement, all variables and given/known data
The cation [CH2=CH-CH2]+ has a delocalized pi network that can be described using Huckel Molecular Orbital Method. Calculate the pi bonding formation energy
2. The attempt at a solution
Using matrix, energy = alpha, alpha + root2 beta , alpha-root2 beta
The pi electron bonding energy(Ebf) is equal to pi electron bonding energy(Epi)-N (alpha), where N is number of carbon atom in the molecules so
Ebf = 2(alpha+root2 beta)-3alpha
but, the suggested answer is N=2 can anyone tell me why N is 2 but not 3
