N2 - In s–p hybridization, the contraction of C−H and C−C bonds as the carbon atom involved varies from sp3 to sp2 to sp is a fundamental and ubiquitous phenomenon in chemistry. Using state-of-the-art quantum chemical computations, this work uncovers that these bonds do not contract due to the increasing percentage of s-character of the hybrid orbital at the pertinent carbon, as is commonly accepted, but, instead, because the steric congestion around this carbon atom decreases as the coordination number goes from 4 to 3 to 2 for sp3 to sp2 to sp, respectively. More information can be found in the Communication by F. M. Bickelhaupt et al. on page 7074. Read the text of the full paper at 10.1002/chem.202100494
