The diagram below shows the bond lengths and hydrogen-carbon-carbon bond angles of ethene: According to valence bond theory, two atoms form a covalent bond through the overlap of individual half-filled valence atomic orbitals, each containing one unpaired electron. Orbital hybridization is the concept of mixing atomic orbitals to form new hybrid orbitals. In ethane (CH3CH3), both carbons are sp3-hybridized, meaning that both have four bonds with tetrahedral geometry. (The hybridization procedure applies only to the orbitals, not to the electrons.) sp² hybridization bond that we formed right here, so here we have an overlap of orbitals, an overlap of an SP three hybrid orbital form carbon, with a un-hybridized S orbital from hydrogen here, and so this is a head-on overlap, so we're sharing electrons here, in this head-on overlap. Each carbon has 4 and each hydrogen 1 for a total of 12 electrons. When we look at the molecules of C2H4 it has 2 CH molecules and 4 H molecules. Have questions or comments?
