The reactions of metastable [C 5 H 10 O] + ˙ radical cations produced by ionization of 4‐penten‐1‐ol are reported and discussed. These [C 5 H 10 O] + ˙ species undergo mainly ethyl radical loss, with smaller contributions of methyl radical and water expulsion. 2 H‐Labelling studies reveal different specificities of hydrogen selection in these three fragmentations. The behaviour of these [C 5 H 10 O] + ˙ ions is compared to those reported previously for isomeric radical cations containing linear alkenyl chains and a terminal hydroxyl group.
