1 pi and 8 sigma bonds.

#### Explanation:

- Every single bond contains 1 sigma bond and 0 pi bonds.
- Every double or triple bond contains at least 1 sigma bond and rest are pi. So, there are 1 sigma and 1 pi in a double bond and 1 sigma and 2 pi in a triple bond.

In propene, which has a structure like this (ignore the angles):

#"H"_3"C"-stackrel("H")stackrel(|)("C")="CH"_2# ...we have 1 double and 6 single bonds (counting both

#"C"-"H"# and#"C"-"C"# bonds).

Therefore, there are 8 sigma bonds and 1 pi bond.
