Great for adding another hydrogen, not so great for building a large complex molecule. Tell me about the best Lewis structure. Its no coincidence that carbon is the central atom in all of our bodys macromolecules. Once you understand hybridization, you WILL be expected to predict the exact shape (Molecular vs Electronic Geometry, to be discussed shortly) as well as the bond angle for every attached atom. Acetone is a widely used organic solvent. As the terminal methyl groups are in tetrahedral shape, the bond angle within the methyl groups is \({\rm{109}}{\rm{.}}{{\rm{5}}^{\rm{o}}}\). The difference in electronegativity between two atomic groups in a compound leads to the formation of polar regions. Due to the presence of a positively charged centre, nucleophilic molecules attack the electrons deficient carbonyl carbon. and sp hybridization, but do understand that you can take it even further to create orbitals like sp, Watch the video below for a quick overview of sp. The hybrid orbitals are more prominent outward Calculated geometries for CH 3 COCH 3 (Acetone). This is shown in the figure below.
