Draw the curved arrows for the reaction mechanism of butanal and :CH2Ph3P+ to give pent-1-ene and triphenylphosphine oxide. Note: Although the oxaphjosphetane may form in one step, show the nucleophilic addition and coordination as separate steps. In the elimination step, provide the arrows that give the resonance structure of triphenylphosphine as shown below.
