I also have two questions that I just need someone to check my answers, I keep second guessing myself!

1. Rank the following carbanions from most stabilized to least stabilized.
 I determined A > B > C (a being most stabilized and C being the least)

2. Rank the alkenes 1-3 in terms of most stable to least stable.
I determined 1 > 2 > 3 (1 being most stabilized and 3 being the least), but I keep going between that and  2 > 1 >3.

@jerrijones great questions and quite provoking

@Jerrijones let's first play around with the structures first moving electrons around. remember in resonance we can only move the pi electrons around. If I remember correctly, we can move the - electrons too on the carbon.
