Disclaimer: Sorry if this is a noob question, I am a high school chem student.

So I was reading my textbook in preparation for the midterm, and it talked about exceptions to the octet rule.

I understand that they exist, and what they are, but how are the chemicals structurally stable?

I also know that they are reactive, but that still doesn't help.

How do they exist?

I was thinking something like only under high pressure/heat, but I can't find anything to back that up. Amazingly, google hasn't help.

Can somebody please explain?

    $\begingroup$ Octet rule is less absolute than you seem to think. Sure, it would be nice to have a full octet, but what if the electrons are just not there? Then we'll have to do without, that's all. $\endgroup$ Jan 15, 2016 at 5:49

  • $\begingroup$ @IvanNeretin Okay. I didn't know that, and assumed the atoms just wouldn't form a molecule in that case. $\endgroup$
