In the hybrid orbital picture of acetylene, both carbons are sp-hybridized. ORBITAL PICTURE OF BONDING: ORBITAL COMBINATIONS, HYBRIDIZATION THEORY, & MOLECULAR ORBITALS ORBITAL COMBINATIONS Atomic orbitals can be combined and reshaped –much like dough– to make other orbitals of different shapes and properties. In this way there exists four Sp-orbital in ethyne. B.Each C-H bond is formed from the interaction between an sp2 hybridized orbital from carbon and an s orbital from hydrogen. Each carbon atom of ethyne has two sp hybridised orbitals. The initial 3D structure of Ethyne was generated automatically by making use of the structure generation engine of Mol-Instincts, a chemical database powered by 41 patented technologies based on quantum mechanics, statistical thermodynamics, QSPR (Quantitative Structure-Property Relationship), and an artificial neural network based AI (Artificial Intelligence). Ethyne molecule consists of two C-atoms and two H-atoms (C 2 H 2). One electron is then placed in each of the sp 2 hybrid orbitals and one electron remains in the 2p orbital. (a) sigma overlaps (b) pi – overlaps. but currently unavailable in Mol-instincts. Carbon-carbon sigma (σ) bond is obtained by the head-on overlapping of the two sp hybridised orbitals of the two carbon atoms. The carbons in ethyne are each sigma bonded to a single hydrogen, but triple bonded to each other. The amount of data and information to be published is up to 10 billion sets. Depending on the number of the single bonds in the target substance, up to tens of thousands of conformers have been generated automatically. The conformer with the lowest potential energy was then used as the starting structure of the geometry optimization. The target chemical substance is typically called “Ethyne”. This molecule is linear: all four atoms lie in a straight line. All the data and information in these webpages are originated from Mol-Instincts or ChemRTP. In the hybrid orbital picture of acetylene, both carbons are sp-hybridized. (b)Which of the four molecules contains the shortest carbon-to-carbon bond? In picture 2 we show the overlapping p orbitals, which form the bond between the two fl uorine atoms, in red and green gradients. Based on the prediction accuracy analysis of entropy, dipole moment, frequency, heat capacity, magnetic susceptibility, polarizability, radius of gyration, van der Waals area, and van der Waals volume, it was concluded that the DFT-B3LYP functional with 6-31G* basis set is an optimal combination, which provides a decent accuracy as well as a reasonable computation time. The carbon-carbon triple bond is only 1.20Å long. Ethene: The bond angle in ethene is 121.3 o. Ethyne: The bond angle in ethyne is 180 o.
