The Lewis structure that is closest to your structure is determined.
The hybridization of the atoms in this idealized Lewis structure
is given in the table below.
### Hybridization in the Best Lewis Structure

-With core pairs on: C 1 C 2 -

The interaction of bonding donor orbital, 3, for C1-H3 with
the second lone pair acceptor orbital, 8, for C2 is 62.3 kJ/mol.

The interaction of bonding donor orbital, 4, for C1-H4 with
the second lone pair acceptor orbital, 8, for C2 is 62.4 kJ/mol.

The total electronic energy is a very large number, so by convention
the units are given in atomic units, that is Hartrees (H). One
Hartree is 2625.5 kJ/mol. The energy reference is for totally
dissociated atoms. In other words, the reference state is a gas
consisting of nuclei and electrons all at infinite distance from
each other. The electronic energy includes all electric
interactions and the kinetic energy of the electrons. This energy
does not include translation, rotation, or vibration of the
the molecule.
Total electronic energy = -77.2806694419 Hartrees
