A strong peak in the mass spectrum of acetone (propan-2-one, CH, COCH,) occurs at m/z 43. What cation does this peak represent? How is it formed? Show by drawing contributing structures that this cation is stabilized by resonance. • Only show specific types of hydrogen atoms: o Hydrogen atoms not attached to carbon atoms Apply formal charges where appropriate. Assign lone pairs and radical electrons where appropriate. • Omit arrows and + signs between structures. . .
