Looks OK to me?

The difference is that this positively charged nitrogen has a full octet.

If we were directly comparing a positively charged nitrogen with an empty orbital versus a positively charged carbon with an empty orbital, you are correct that carbon would be more stable.

Great work dude… You explain everything in simple words.. Easy to understand… Sometimes that is the hardest thing in organic chemistry

I thought, since N is more electronegative than C, the +ve charge will be more stable on C.

Thanks for the Website.

I wanna really understand the anti-bonding, bonding, and the *. My professor does research and goes really in depth conceptually on exams.

Thank you, i appreciate the work you do.

That means that if we really want to understand a reaction, we have to understand where the electrons are (and aren’t). […]

I’ve been perusing your site for the past few weeks, since your comment on my post (thanks for the link, btw)

In your final bullet point, I would argue that curved arrow notation is not the only form of accounting we use, since I’ve always considered the concept of “formal charge” as a form of accounting myself. :)

Crap you are right. Fixed! thanks for the spot.
