Scheme with the main gas-phase formation and destruction reactions of small hydrocarbons predicted by our model of the Orion Bar PDR at AV ≃ 1.5 (close to their abundance peak). Reactions with activation energy barriers are indicated with red arrows. The blue arrows are barrierless hydrogenation reactions.
