WebApr 30, 2024 · The strain energy of spiropentane (62.9 kcal.mol), however, significantly exceeds that of two cyclopropane rings (54.8 kcal/mol). Wiberg has noted that this happens because the central carbon is forced to adopt sp 3 hybridization, whereas in cyclopropane, the carbons are closer to sp 2 hybridization . A similar phenomenon is observed for ... Web2. what is e-p geometry of a molecule with a steric number of 4? Answer: The angles between electron domains are determined primarily by the electronic geometry (e.g., 109.5° for a steric number of 4, which implies that the electronic shape is a tetrahedron) These angles are adjusted by the hierarchy of repulsions: (lone pair - lone pair ... philips bluetooth portable speaker
