Re: Pi and Sigma Bonds
I think it might be the other way around, but someone can correct me if Im wrong because im not sure.

Re: Pi and Sigma Bonds
Correct! Sigma bonds are formed whenever atomic orbitals overlap along the bond axis. Pi bonds, on the other hand, form whenever p orbitals overlap and appear perpendicular to sigma bonds. Because of this, pi bonds will only occur if sigma bonds are present.
I'll link a video that gives more of a visual explanation!

Re: Pi and Sigma Bonds
Hey! Any bond is a sigma bond. A pi bond counts as a double or triple bond. So, yes. Within every pi bond is a sigma bond.

Re: Pi and Sigma Bonds
I'm a little confused but this could be just me overanalyzing terminology. Sigma bonds are not literally within pi bonds, correct? For example, in a double bond, is one of the two is sigma while the other is pi or are they merged?

Re: Pi and Sigma Bonds
Yes! Pi bonds only exist with sigma bonds! Sigma bonds are every single bond, and then when there is a double bond there is one sigma and one pi bond. Triple bonds contain on sigma bond and two pi bonds.

Re: Pi and Sigma Bonds
Hi Diego,
You are correct! Pi bonds can only exist when there are sigma bonds. For example, when there is a double bond, there is one sigma bond and one pi. When there is a triple bond, there is one sigma bond and two pi bonds. Sigma bonds are formed whenever atomic orbitals overlap along the bond axis. Pi bonds are formed whenever there's an overlap of parallel p-orbitals on adjacent atoms.

Re: Pi and Sigma Bonds
Yes, but I think you worded it a bit off. Instead of saying there is a sigma bond in every pi bond I think you meant to say there is a sigma bond in every bond. However, yes, there is a single sigma bond in double and triple bonds.

Re: Pi and Sigma Bonds
Yep so for double there's one sigma and one pi and for triple bond there's one sigma and two pi.

Re: Pi and Sigma Bonds
Pi bonds only exist with a sigma bond alongside it since sigma is always the first bond.

Re: Pi and Sigma Bonds
Yes, if there ever is a pi bond, there is also a sigma bond. For every bond after a single bond, you tack on a pi bond. But you only start introducing pi bonds after the inclusion of one sigma bond.

Re: Pi and Sigma Bonds
Yes, this is because the pi bond is only present after there is already a sigma bond. For example, in a single bond, it is only a sigma bond, in double bonds, there is one sigma and one double bond, and in triple bonds, there is one sigma bond and two pi bonds.

Re: Pi and Sigma Bonds
Yes, since pi bonds result from double bonds and double bonds consist of a sigma bond and a pi bond.
