ORBITAL STRUCTURE OF ETHYNE | |
COMPOSITION OF ETHYNE MOLECULE: Ethyne molecule consists of two C-atoms and two H-atoms (C2H2). NATURE OF HYBRIDIZATION: In ethyne molecule, each carbon atom is Sp-hybridized. Due to Sp-hybridization each carbon atom generates two Sp-hybrid orbitals. In this way there exists four Sp-orbital in ethyne. These Sp-orbital are arranged in linear geometry and 180o apart. Remaining py and pz unhybrid orbitals of each carbon atom lie perpendicular to the plane of Sp-orbitals. SIGMA BOND FORMATION: One Sp-hybrid orbital of each carbon atom overlaps to produce one sigma bond between two C-atoms.The remaining one Sp-orbital of each C-atom overlaps with one H-atom to produce sigma bond. Pi-BOND FORMATION: Py and Pz orbital of two carbon atoms are un-hybrid and make parallel overlapping to produce pi-bond. BOND LENGTH: The C--H bond is 1.09A and C-C is 1.2A.o. BOND ANGLE: HCC bond angle is 180o. | |
