Formaldehyde
The bond length of formaldehyde was was find using different
energy levels. The lengths between the two hydrogens, carbon, and oxygen were found using
AM1 energy level.
The next length was found using energy level 6-21G.
The next length was found using energy level 6-31G, which is a higher level of theory than 6-21G.
The final energy used to find bond length between the chlorine and
oxygen ion was DZV, this was the highest level of theory used to detect
bond length.
The Highest Occupied Molecular Orbital (HOMO) is the 8th orbital as determined by adding all the electrons up and dividing them
by two as there are two electrons for each orbital.
The Lowest Unoccupied Molecular Orbital (LUMO) is the orbital just one
above the Highest Occupied Molecular Orbital, for formaldehyde that orbital is 9.

The electrostatic potential of the molecule shows where the highest and
lowest potentials are in the orbitals. The blue color shows where the
electrostatic potential is the highest while the red shows where it is
the lowest.
The partial atomic charges of each atom are calculated via the
distribution of the electrons in the chemical bond between the four atoms

From our experimental data, the dipole moment
of formaldehyde was found to be 3.158 Debye. Using NIST, the
experimental dipole moment is said to 2.330.4
