The curved arrow notation for the given McLafferty rearrangement step is to be provided. Concept introduction: A carbonyl compound containing at least one γ- hydrogen undergoes McLafferty rearrangement. The mechanism involves the transformation of γ- hydrogen to carbonyl through radical coupling where it forms C=C bond between γ and β by breaking the sigma bond between β and σ carbon. This results in ejection of alkene to form enol radical cation. For the mechanism of radical reactions, the curved arrows with one hook can be used as it indicates the movement of one electron.
