Homework Help: Chemical Bonding in Hydrocarbon

  1. Feb 28, 2006 #1
    While studying chemical bonding for methane,ethyne etc., I have made the following assumption to help me to remember the sigma bond, pai bond, and hybrid orbitals.
    1. Every single covalent bond around a carbon atom is a sigma bond.
    2. Only one of the bond in double and triple covalent bond is a sigma bond. The others are pai bond.
    3. If there are 4 sigma bond around a single carbon atom, sp^3 hybid orbitals are involved.

    Is my assumption wrong? Or they are just suitable for certain hyddrocarbon?

    Actually it is not necessarily true that there is atleast one sigma bond in a double or triple bond. This is because since the bonds repell each other, you are going to have two pi bonds rather than a sigma and a pi. I am not completely sure though.

    Thats right, if there are 4 bonds from a carbon, they are sp3.
