dear sir, where would i get information and explanation on some characte characteristic f features on pi bonds to answer questions on how many sigma and pi bonds are present in some hydrocarbon molecules.

For every single bond, you have one sigma bond.
If you have a double bond, you have one sigma bond and one pi bond.
If you have a triple bond, you have 1 sigma bond and two pi bonds.

So to find the total number of pi bonds in the molecule, you need to identify the number of double and triple bonds in the molecule.
No. of pi bonds = (No. double bonds) + (2 * No. of triple bonds)

It would help to draw out the structure with the appropriate bonds between the atoms.
