Homework Help: Total bonds in ethyne

  1. Sep 15, 2012 #1
    1. The problem statement, all variables and given/known data
    In the hybradization of ethyne molecule, how many σ and ∏ bonds are being formed?

    3. The attempt at a solution
    Since, there is a triple bond between the carbon atoms, it should form 2 ∏ bonds and 1 σ bond.
    Relatively there will be 2 other σ bonds between Carbon-Hydrogen.

    So, all together, there are supposed to be 3 σ and 2 ∏ bonds.
    Want to know if the above theory is right?

    That's correct.

    Yes. Perfect. The only problem that happens in multiple choice questions is that students might forget to mention that the triple bond also contributes a sigma bond.
