Showing Electron Arrangement

Postby Jasmine_Esparza_2A » Sun Feb 26, 2017 9:08 pm

I noticed in the course reader on page 83 that there is a difference in the arrows used to show the movement of one electron and two electrons.
Is this important? On the quiz will we need to strictly use a one sided arrow to show only one electron moving?

Yes, this is important, as which arrow you use gives the e- arrangement; as stated in the course reader, the arrows give more detail to an organic reaction mechanism.

A "full triangle" at the tip of the arrow denotes a 2 e- rearrangement, while a "half triangle" at the tip of the arrow denotes a 1 e- rearrangement.

On Pg. 87 of the course reader, we can see that the direction of the arrow and where the arrow begins both matter as well.
