The formula CH2O describes a molecule made of 1 carbon atom, 2 hydrogen atoms and 1 oxygen atom. It is written in Hill notation: carbon first, then hydrogen, then the other elements in alphabetical order. The formula tells you which atoms are present, not how they are connected, which is why several different chemicals can share it.

Frequently asked questions
What is the molar mass of CH2O?
The molar mass of CH2O is 30.03 g/mol, calculated from standard atomic weights for 1 carbon atom, 2 hydrogen atoms and 1 oxygen atom. The monoisotopic mass is 33.0265 Da.
How many compounds have the formula CH2O?
CompoundList lists 9 compounds with the molecular formula CH2O, including Formaldehyde, (2H)Formaldehyde, Formaldehyde-13C (20% by weight in water). Compounds that share a formula are isomers. They contain the same atoms arranged differently, so their properties, uses and prices can be very different.
What is the degree of unsaturation of CH2O?
CH2O has a degree of unsaturation of 1. That is the total number of rings and pi bonds (a double bond counts as one, a triple bond as two) in any structure with this formula.
