Trending Questions. From Google: The steric number of a molecule is the number of atoms bonded to the central atom of a molecule plus the number of lone pairs on the central atom. This is also known as the Steric Number (SN). Let’s find out the Hybridization of CO2. Steric number (SN) = No. However, because of the resonance delocalization of the lone pair, it interconverts from sp3 to sp2 as it is the only way of having the electrons in an aligned p orbital that can overlap and participate in resonance stabilization with the pi bond electrons of the C=O double bond. The number is calculated mainly for the central atom of the compound which is then used to predict the geometry of the compound. If you observe keenly, there is a sigma bond at the right side of the Oxygen. CO2 Hybridization. SP Hybrid Orbital Model . After that, the application of VSEPR theory takes place with the Lewis structure. This content is for registered users only.

Examples of how to use “steric” in a sentence from the Cambridge Dictionary Labs C1 – SN = 3 (three atoms connected), therefore it is sp2, C2 – SN = 3 (three atoms connected), therefore it is sp2, O4 – SN = 3 (1 atom + 2 lone pairs), therefore it is sp2, O5 – SN = 4 (2 atoms + 2 lone pairs), therefore it is sp3, C6 – SN = 4 (4 atoms), therefore it is sp3, C7 – SN = 4 (4 atoms), therefore it is sp3, N8 – SN = 4 (3 atoms + 1 lone pair), therefore it is sp3, C9 – SN = 2 (2 atoms), therefore it is sp, C10 – SN = 2 (2 atoms), therefore it is sp. Count its valence electrons. Another way to look at molecular geometry is to assign the shape of the molecule according to steric number: SN = 2 is linear. In other words, the steric number represents the number of lone pairs present on, and the number of atoms bonded to the central atom of a molecule. Now, let’s check and see if we have octets.
