Chapter 8 - Mechanisms - 8.1 Curved Arrows - Problems - Page 170: 8.2


This arrow is going from a bond to a lone pair.

Work Step by Step

1. Identify where the tail of the arrow is: The tail is clearly on a bond. 2. Identify where the head is going to: The head is going to a Bromine atom. When the electrons are going to an atom, they can: - Be a lone pair - Make a bond In this case, making a bond doesn't make much sense, since the arrow is coming from a bond that the Bromine was making. Therefore, this arrow is going from a bond to a lone pair.
