This study investigates the carbonyl oxygen's lone pairs in HCHO, concluding they are sp hybridized with distinct p<sub>y</sub> and sp orbital lone pairs based on MO theory and UV spectral data.

The preprint addresses whether the two lone pairs of electrons on the carbonyl oxygen atom in formaldehyde (HCHO) are identical, motivated by differing textbook viewpoints. Using molecular orbital (M.O.) theory alongside ultraviolet (UV) spectral data, the authors conclude that the carbonyl oxygen can be sp-hybridized with two different types of lone pairs: one lone pair associated with a pπ orbital and the other with an sp hybrid orbital. As a short report/preprint, it has not been peer reviewed, which limits how definitively its conclusions can be evaluated. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

Different opinions about the nature of two lone pairs on oxygen atom of carbonyl group in HCHO promote the present authors to undertake the study on this matter. Here opinions of different text books as stated by the authors are represented in brief and systematic manner to conclude finally that carbonyl oxygen may be sp hybridized with two different types of lone pairs as supported by M.O. theory and uv spectral data [one lone pair on p y orbital and another lone pair on sp hybrid orbital] on oxygen atom.
