- Examine the sigma bonding in ethene. What types of orbitals does each C atom use when forming sigma bonds to the H atoms? s orbial p orbitals Ohybrid orbitals Submit What type of orbital does each C atom use to form a sigma bond to the other C atom? s orbial p orbitals hybrid orbitals O Submit Now examine the pi bonding in ethene. What types of orbitals on the C atoms are used to form the pi bond? Os orbital p orbitals hybrid orbitals Submit(a)The concept of hybridization was first proposed by Linus Pauling in 1931, that explain about the concept of mixing orbitals to form new hybrid orbital suitable for the pairing of electrons to form chemical bonds. Draw the kekule structure of a compound that contains only carbon and hydrogen atoms that has: (1) One sp hybridize carbon, two sp? hybridized carbons and two sp hybridized carbon (ii) Two sp' hybridized carbon and two sp hybridized carbons (ii) Two sp? hybidized carbons and two sp hybydized carbon4. Octatetraene, C8H10, is an 8-membered linear carbon chain with alternating single and double bonds. As a result, each carbon is left with an unhybridized p-orbital containing one electron. This problem will take you through steps to construct and fill the molecular orbital diagram for octatetraene based on the way these different p-orbitals can come together. a) The various molecular orbitals formed from octatetraene’s 8 unhybridized p-orbitals are shown on the next page. Draw the nodal planes for each molecular orbital. Hint: A nodal plane is a line through the molecule that denotes the sites of destructive interference. An example is shown below with ethylene. b) Based on the nodal planes, arrange the energy levels corresponding to the 8 molecular orbitals on the energy level diagram (label them using the numbering provided on the left side of the molecular orbitals) on the next page, in order of lowest to highest energy. c) Populate your molecular…
