Question

Define sigma bond and pie bond which is stronger in chemistry

Answer 1

Sigma bond is the single bond formed between the molecules
Pie bonds are double formed between molecules.

Pie bonds are formed by the overlapping of p-p orbital whereas sigma bonds are formed by the overlapping of s-s orbital.

When we talk about the single or double bonds, the double bonds are more stronger.

But in case of sigma or pie bond, sigma bonds are more stronger.

I hope this will help.

Answer 2

Head to head overlapping is more efficient and thus sigma bonds are much stronger.

In pie bonds side wise overlapping is found that is not so efficient and thus pie bonds are weaker than sigma bonds.

hope this helps u❤️
