Group 13

Postby ALee_1J » Sat Nov 07, 2020 11:27 am

Are Group 13 elements always electron deficient or does it depend? Also, does electron deficient (the way that Dr. Lavelle uses it) mean that the atom/element can be without an octet?

I believe that all group 13 elements are electron deficient and act like Lewis acids. Not entirely sure on the second question but I think electron deficient just means the atom doesn't have enough electrons to fill an octet, but compounds with boron and aluminum are exceptions to the octet rule.

Some of the Group 13 elements can sometimes exist in compounds where they have 8 valence electrons, such as BF3NH3, meaning they are not necessarily always electron deficient.

I believe that yes, electron deficient means that the atom/element can be without an octet as Dr. Lavelle uses it.

All group 13 elements are exceptions/electron deficient, but I think we're only going to focus on Boron and Aluminum in this class
