How to tell the hybridization

Postby Genisis Cabral » Sun Nov 19, 2017 7:54 pm

When looking at the lewis structure of a compound such as ethane, how would you use that too quickly tell what the hybridization of the compound is? Is there a quick method to do so?

You just look at how many electron domains are around the central C. If you have more than 1 C then you look at the hybridization around each one of them separately.

Hi! Most helpful to me has been that the hybridization depends on the shape. So tetrahedral shapes will have a certain hybridization, as will linear, octahedral, trigonal bipyramidal, et cetera. So writing the Lewis structure would be a great first step!

A quick way to determine hybridization is to look at the electron domains. Generally if a molecule has less than 5 electron domains, the hybridization has the number 1 less than the amount of domains. For example 4 e- domains: SP3, 3 e- domains: SP2, 2 e- domains: SP. Thats just a quick way to check if you have the right hybridization. Other than that I would still suggest that you know the concept behind it and how to determine the hybridization physically, like through drawing and finding the shape.

To tell the hybridization, I usually look at the number of electron dense areas. The total number will help you identify the hybridization by looking at the exponents of each letter. For example, an atom with four electron dene areas will have a hybridzation of sp^3.
