CONCEPT: THE MECHANISM- ELECTRON MOVEMENT Reactive molecules share electrons to become more stable. _________ are used to show which direction they are going. ● Arrows always move from regions of _________ electron density to _________ electron density ● By that logic, _________________________ must always attack ____________________________ ● Each attacking arrow represents ____ electrons being shared. Replace that arrow with a new ____ - __________ EXAMPLE: Determine the initial direction of electron movement by drawing the first arrow of each mechanism:
a.

□ Bond breaking is sometimes also required in mechanisms, but only when it is required to preserve octets. There are two ways to break chemical bonds:
EXAMPLE: Identify which of the above reactions require bond breaking and/or more arrows to satisfy all octets.
