Curved Arrows (for reactions) - Master Organic Chemistry

WebCurved arrows are a formal notation to help us understand the electron flow in organic reactions. This makes it easier to keep track of the bonds forming and breaking during the reaction as well as visualizing and explain more advanced features such as the region and stereochemistry of certain reactions. WebTheir movement is shown using a curly arrow. At the same time, the C-Br bond breaks and the electron pair is transferred to the bromine atom, forming a bromide anion (Br-). Once again, electron movement is shown using a curly arrow. Note that the bromide ion also has a lone pair of electrons, represented by two dots. eastman auto repair rochester mn https://aladinweb.com
