WebJul 24, 2015 · The middle C atom has two bonds going to the other carbons, so it has 4 − n = 4 −2 = 2 hydrogen atoms. In the above molecule, the three C atoms on the right hand side each have one bond to a central carbon. Since 4 − n = 4 −1 = 3, they each have 3 H atoms ( CH3 groups). The central C atom is bonded to the three methyl groups and to the ... major to minor towingWebThe most potent tumorigen identified among the polycyclic aromatic hydrocarbons (PAH) is the nonplanar fjord region dibenzo[a,l]pyrene (DB[a,l]P).
