No.

Well I suppose it depends upon what you mean by different.

The double bond comprises one sigma bond formed from sp² hybrid orbitals and one pie bond formed from the remaining p orbital.

The triple bond comprises one sigma bond formed from sp hybrid orbitals and two pie bonds formed from the remaining p orbitals.

But each individual pie bond is equivalent.

It would be good if some of your countrymen would step in here and tell you that it doesn't hurt to respond to those who have genuinely put themselves out to help you.

Yeah that's why I've stopped helping. We get nothing back.

@studiot To reiterate the question, the one pie bond in a double bond and 2 pie bonds in a triple bond are they different.

I get the hybridization.

Do you ?

I hope so.

Here is a more detailed explanation of why the bonds are this way.

It is to do with the geometry of the different configurations.

Note the double bond has a planar structure whilst the triple bond has a linear structure.

So there is only room for the lobes of the Pz orbital to stick out top and bottom in the double bond hence only the z Pie orbital (two separated lobes ) is formed.

In the triple bond the Pz orbital sticks out top and bottom and the Py orbital sticks out side to side forming the other Pie bond.

So that is what I mean when I say theya re equivalent.

The article gives specific values for the effects on bond strength.

Clicking on one of the pictures will give a bigger version for ease of reading.

This response is more like I would expect to see in a discussion.

So do you understand why different configurations with different hybridisations are allowable ?

@studiot thanks @exchemist
