# of sigma and pi bonds [ENDORSED]

[Jasmine Botello 2F]

So there is always one sigma bond and then all other bonds created after that are going to be pi bonds??

[Nicole Nikolov 1K]

Yes. This is true because a bond can only have one head-on overlap. For double and triple bonds, the additional bonds will be pi bonds and will form perpendicular to the sigma bond.

[Michaela Capps 1l]

And in each double/triple bond, the first bond will be a sigma bond, and then the successive bond(s) will be pi bonds

[Yixin Angela Wang 2H]

So basically, the first bond formed is always a sigma bond, and the second or third bond, if there is one, is always a pi bond?

[Chem_Mod]

Yes. The first bond is always sigma, and any after are pi bonds.
