    How many sigma (σ) bonds are in a single bond?

    How sigma (σ) bonds are in a double bond?

    Even after answering those questions, I don't think the OP's answer would change. I would say that the OP is correct and the book has an error.

    1 σ in single bond, 1 σ and 1 pi bond in double bond.

    I would agree that OP is correct and that the number of C-C sigma bonds is 8.
