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"_2H3C−H∣C=CH2 ...we have 1 double and 6 single bonds (counting both
"C"-"H"C−H and"C"-"C"C−C bonds).
Therefore, there are 8 sigma bonds and 1 pi bond.
