WebWhat correlation, if any, do you find between bond order and bond strength. Briefly summa-rize your reasoning. As bond order increases, the strength of the bond increases as well. The compounds H 3CCH 3, H 2CCH 2, and HCCH show this trend nicely. The bond energy for Cl 2 is shown on the other side of this page. The bond energy for the Br–Br ... WebThe sigma-bonds look like this: HCCH! C(sp)-H(1s)! C(sp)-H(1s)! C(sp)-C(sp) Each carbon has a 2p y and a 2p z orbital leftover. The 2p y orbitals overlap to make one π-bond, while the 2p z orbitals overlap to make a second pi-bond: HCCH! C(2py)-C(2py) HCCH! C(2pz)-C(2pz) The energy diagram shows the relative energies of all of the bonds ...
