Why is Lewis Structure A Better for Diazomethane?

Click For Summary
SUMMARY

The discussion centers on the Lewis structure of Diazomethane, specifically why the first structure (designated as A) is more acceptable than the alternative. The key reason identified is that the neutral carbon in structure A better reflects the compound's reactivity, particularly in the formation of methyl esters with acids. In contrast, the alternative structure leads to unfavorable repulsion between two negative charges, making it less stable and acceptable.

Homework Statement



I was taking a practice exam, and it asked for the "acceptable lewis structure for Diazomethane"

I had narrowed it down to two possible results but can't for the life of me figure out why one is more acceptable than the other. I attached a picture of the two choices.

I know the answer is A, the first choice. But I don't know why!

anyone? :-/
 
I think it's as simple as the form with the neutral carbon reflecting better the reactivity of the compound, as in e.g formation of the methyl ester with acids. Otherwise you may get repulsion of two negative charges which is unfavourable.
