So I encountered this question in Kaplan. Take a look at it before you readon.











I thought the answer would be c because the negative charge is on the more electronegative atom. But kaplan says it's b. I guess b has the advantage that the +/- charges are less separated but I still thought the Nitrogen having the negative charge would win over. Any other thoughts?

look at C... that carbocation is so so unstable. its not even a primary. it wouldnt form that. i would say C is wrong.

Oops. I remember now. Full octet definitely comes before negative charge on the more e-negative. Weird how none of the given structures is the actual most stable one (H2C=N=N).....

Thanks
