Cyclopropenyl System:
In case of cyclopropenyl, N=3.
The corresponding energy level diagram is given below:
In case of cyclopropenyl, N=3.
The corresponding energy level diagram is given below:
- Cyclic C3H3 radical contains a total of 3 electrons. Out of which 2 electrons are present in Eo and 1 in E1.
- The total π electron energy (E) of cyclic C3H3 radical is given by,
- Now, Another related term is π bond formation energy which is the energy released when a π bond is formed.
- Since the contribution of α is the same in the molecules as in the atoms, so we can consider the energy of two electrons, each one in isolated and non-interacting atomic orbitals as 2α, then the π bond formation energy becomes,
Eπ(bond formation) = E - nα
where, n is the number of C atoms.
where, n is the number of C atoms.
- For, cyclic C3H3 radical (n=3) π bond formation energy is
Eπ(bond formation) = 3α+3β - 3α
= 3β
= 3β
- The delocalization energy of the molecule in the ground state is,
= 3β−2β (2β is the total π bonding energy on the formation of the ethylene molecule)
= β
Hence, the delocalization energy of the molecule in the ground state (in units of β, where β is Hückel's constant for interaction energy) is 1.
= β
Hence, the delocalization energy of the molecule in the ground state (in units of β, where β is Hückel's constant for interaction energy) is 1.
