Friday's Lecture July 12, 2019

Postby Karolina herrera1F » Fri Jul 12, 2019 7:22 pm

Today in lecture Dr. Lavelle began talking about how B completed the octet of trifluoride, but I do not understand when trifluoride will want B to complete it and when not? If it even wants it to complete it under certain conditions? Can someone explain please, thank you. :)

According to Dr. Lavelle, Boron is one of those exceptions to the octet rule. It is important to note that Boron often only makes three covalent bonds.

I think it's a matter of when the atom is most stable, so we know ideally that an atom would like to fulfill the octet rule, using double bonds, single bonds, etc. or lone atom pairs but it's just a matter of when B is the central element, it will want to be as stable as possible.
