WebDec 20, 2010 · What is the molecular formula of the compound CH2 with molar mass 42.0? The unit CH2 has a gram atomic mass of 12.011 + 2(1.00794) or about 14. 42.0/14 = 3; therefore the molecular formula is C3H3 Methylene (IUPAC name: Methylidene, also called carbene or methene) is an organic compound with the chemical formula CH 2 (also written [CH 2]). It is a colourless gas that fluoresces in the mid-infrared range, and only persists in dilution, or as an adduct. Methylene is the simplest carbene. It is usually detected only at very low temperatures, or as a short-lived intermediate in chemical reactions.
