H2CO, not HCOH on Molecular Dataset

PennyLane Feedback
1

Pennylane’s molecular dataset shows a structure of H2CO (metanal) being associated to a HCOH labeling, which refers to a metanol radical without two hydrogen atoms under IUPAC standards.

Non-hydrocarbons are labeled in dense form with the most electropositive atom coming first, whereas hydrocarbons privilege the organic functional, so metanal has two acceptable writings: H2CO or CH2O, but not HCOH, since it evidences an OH group that is absent in the structure shown on the webpage.

It is confusing whether the molecule refers to a metanal or metanol radical. Could you please fix it?

Hi @Den, thank you very much for your feedback!

Our team will get back to you with a clarification soon. Please let us know if you find any other issues such as this one.

Hi @Den,

Thanks for catching this. The dataset contains data for CH2O, methanal/formaldehyde. So the image is the correct one.

We will update the title for this dataset to “CH2O” soon. Thanks again!
