Answer

The pi bond moved to the oxygen, forming a lone pair. The carbon that was connected to the pi bond will get a positive charge, and the oxygen, a negative charge.

Work Step by Step

1. The electronegative atom is the oxygen. 2. Draw the arrows: Follow the same pattern we have learned in the chapter. (The pi bond electrons will move to the electronegative atom.) 3. Do the changes based on the arrows. * Don't forget the formal charges!
