Formaldehyde
HCHO is the chemical formula of formaldehyde.
Formaldehyde (HCHO) is the simplest aldehyde. It is also known as methanal (NOT methanol) or paraform.
The oxidation number of carbon in formaldehyde (HCHO) is +2. In this molecule, oxygen has an oxidation number of -2, and hydrogen has an oxidation number of +1. By applying the rules for assigning oxidation numbers in a compound, we can determine that carbon has an oxidation number of +2.
In C6H14 (hexane) and H2O (water), there are London dispersion forces, dipole-dipole interactions, and hydrogen bonding. In HCHO (formaldehyde), there are dipole-dipole interactions and London dispersion forces. In C6H5OH (phenol), there are hydrogen bonding, dipole-dipole interactions, and London dispersion forces.
HCH2O does not exist as a chemical compound. HCHO (formaldehyde) is a weak acid.

The Time-Weighted Average (TWA) for formaldehyde (HCHO) is 0.3 parts per million (ppm) over an 8-hour workday. This is the maximum average concentration of formaldehyde that a worker can be exposed to over a typical 8-hour work shift without adverse health effects.
Formaldehyde (HCHO) primarily exhibits dipole-dipole interactions due to its polar nature, as it has a significant difference in electronegativity between the carbon and oxygen atoms. Additionally, it can participate in hydrogen bonding because of the presence of a hydrogen atom attached to the carbon, which is adjacent to the highly electronegative oxygen atom. However, hydrogen bonding in formaldehyde is weaker than in substances like water. Overall, the dominant intermolecular forces in HCHO are dipole-dipole interactions, with some contribution from hydrogen bonding.
