Na, NH3 H3C—C=C—CH3 CH3 H3C Alkynes are reduced to trans alkenes by a process called dissolving metal reduction. The reaction uses sodium or lithium metal as the reducing agent and liquid ammonia as the solvent. The method is specific in the formation of trans alkenes from alkynes. The method involves two successive transfers of single electrons from the alkali metal to the triple bond, with abstraction of protons from the ammonia solvent. Draw curved arrows to show the movement of electrons in this step of the mechanism. Arrow-pushing Instructions GeX XT Na. CH3 CH3 Nat H3C IO H3C IO
