In organic chemistry, a methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms, having chemical formula CH3. In formulas, the group is often abbreviated as Me. This hydrocarbon group occurs in many organic compounds. It is a very stable group in most molecules. While the methyl group is usually part of a larger molecule, bounded to the rest of the molecule by a single covalent bond (−CH3), it can be found on its own in any of t… city of hamilton property standards bylawWeb11 apr. 2024 · Published: April 11, 2024 at 12:34 a.m. ET.
