4/1/2024 0 Comments Sp3 sp3dO4 – SN = 3 (1 atom + 2 lone pairs), therefore it is sp 2 So now, let’s go back to our molecule and determine the hybridization states for all the atoms.Ĭ1 – SN = 3 (three atoms connected), therefore it is sp 2Ĭ2 – SN = 3 (three atoms connected), therefore it is sp 2 Once you know how to determine the steric number (it is from the VSEPR theory), you simply need to apply the following correlation: Notice that multiple bonds do not matter, it is atoms + lone pairs for any bond type. This is also known as the Steric Number (SN).īelow are a few examples of steric numbers 2-4 which is largely what you need to know in organic chemistry: By groups, we mean either atoms or lone pairs of electrons. The first thing you need to do is determine the number of the groups that are on each atom. Let’s say you are asked to determine the hybridization state for the numbered atoms in the following molecule: ![]() ![]() The hybridization theory is often seen as a long and confusing concept and it is a handy skill to be able to quickly determine if the atom is sp 3, sp 2 or sp without having to go through all the details of how the hybridization had happened.įortunately, there is a shortcut in doing this and in this post, I will try to summarize this in a few distinct steps that you need to follow.
