WebCurly arrowsalways flow from electron rich to electron poor (i.e.nucleophile to electrophile) Curly arrowsmust startfrom either lone pairsor bonds (σ or π bonds) Therefore, it's a good idea to draw in all the lone pairs as two dots e.g. or especially on oxygen or nitrogen atoms WebJan 21, 2024 · When asked to draw a mechanism, curved arrows should be used to show all the bonding changes that occur. A few simple lessons that illustrate these concepts can be found below. Lesson 1 If we remove the pair of electrons in a bond, then we BREAK that bond. This is true for single and multiple bonds as shown below:
