Sigma and Pi Bonds

[DanielleNario1A]

If a molecule given has 2 double bonds and 1 triple bond, would the number of sigma bonds be 3 and the number of pi bonds be 4?

[Shash Khemka 1K]

Yeah, that's correct. A single bond will have 1 sigma bond, 0 pi bonds. A double bond will have 1 sigma bond, 1 pi bond. A triple bond will have 1 sigma bond, 2 pi bonds. Using this reasoning, we can say that a molecule with 2 double bonds and 1 triple bond will have 3 sigma bonds and 4 pi bonds.

yes. One double bond consists of one sigma bond and one pi bond, and one triple bond consist of one sigma bond and two pi bonds.

[Duby3L]

Yes, that is correct for every double bond there is one sigma and one pi bond and for every triple bond there is two pi bonds and 1 sigma bond.

[Andreana Vetus 1A]

Yes. Every bonding region has one sigma bond. All additional bonds are pi bonds.

[KatrinaPho_2I]

Yep! Every first bond is a sigma bond. Any other bond added on top of the first ones are considered pi bonds.

yes! a double bond contains 1 sigma and 1 pi bond while a triple bond contains 1 sigma and 2 pi bonds so just add those up!!
