Bouncing Arrows Fix Ambiguous Mechanisms in Seconds! (Alkene Additions)

Bouncing arrows fix the big problem with curved arrows: ambiguity when the arrow starts at a bond. In this tutorial video, you’ll see how a simple “FROM HERE” bounce makes alkene additions, Markovnikov reactions, rearrangements, and EAS directors unambiguous.
