Share to Twitter Share to Facebook Share to Pinterest. Figure 2: Chemical Structure of Ethene. Remember that hydrogen atoms always go on the outside of a Lewis structure and that they only need two valence electrons for a full outer shell. hydrogen and carbon atoms effectively have full outer shells in forming the by the four strong C–H carbon–hydrogen single covalent bonds and one C=C covalent bonds (it has a planar shape, its completely flat!, the H–C=C and H–C–H Each carbon atom is also attached to sufficient hydrogen atoms to produce a total of four single covalent bonds about itself. c. Sketch the molecule showing the predicted bond angles. asked Oct 11, 2019 in Chemistry by Deepak01 (58.6k points) carbon and its compounds; class-10; 0 votes. Since all the atoms are in either period 1 or 2, this molecule will adhere to the octet rule. They follow the duet rule (2 electrons). Lewis Electron Dot Structure of Ethylene (Ethene), C 2 H 4 This time, the carbon atoms share 2 electrons with each other and 2 electrons with 2 hydrogen atoms. Based on this structure, predict the H-C-H bond angle. Acetylene is an unsaturated hydrocarbon with a triple bond. Ethene is actually much more interesting than this. Observe the Lewis dot structure representing the electronic structure in ethene. Each carbon requires a full octet and each hydrogen requires a pair of electrons. A double covalent bond is a covalent bond formed by atoms that share two pairs of electrons. Based on this structure, predict the H-C-H bond angle. Ethene is the first member of the homologues series of alkenes. An orbital view of the bonding in ethene. Hydrogen can only form 1 bond.
